Description of problem: Directory quota is ignored by command "cp *"


Version-Release number of selected component (if applicable): glusterfs 3.6.2


How reproducible: 100% reproducible


Steps to Reproduce:

1. Have quota on /cifs_share/Dir3:

                  Path                   Hard-limit Soft-limit   Used 
Available  Soft-limit exceeded? Hard-limit exceeded?
---------------------------------------------------------------------------------------------------------------------------
/cifs_share/Dir3                          20.0MB       80%      17.0MB   3.0MB 
           Yes                   No



2. Check contents of the /Dir3 
 ls /samba/nas-volume-0001/cifs_share/Dir3/

glusterfs-3.2.7.tar  glusterfs-3.3.0.tar.gz  glusterweb-f88e119.tar.gz



3. Copy 30 files with total size of 165MB to the /Dir3

cp *.log /samba/nas-volume-0001/cifs_share/Dir3/

4. Check quota:

gluster volume quota nas-volume-0001 list
                  Path                   Hard-limit Soft-limit   Used 
Available  Soft-limit exceeded? Hard-limit exceeded?
---------------------------------------------------------------------------------------------------------------------------
/cifs_share/Dir3                          20.0MB       80%     182.7MB  0Bytes 
           Yes                  Yes


5. Check files at the /Dir3

 ls /samba/nas-volume-0001/cifs_share/Dir3/

                                                      sfcm.log          
sfvs_ports.log


6. Files at the source directory:

 ls *.log

admin.log       ffmirrord.log           isns_update.log 
nas_vol_seg_repair-nas-metadata-on-SC-10.10.63.182_nas-metadata.log  sfapi.log 
        sfcm_handler.log      sffe_monitor.log  traps.log
dbUpgrade.log   fo_handler.log          lu_stats.log     sfapi_handler_9003.log
                                              sfcmd_iping.log    sfcm.log      
       sfvs.log          utils.log
do_command.log  fo_handler_service.log  ms_service_.log  sfapi_handler.log     
                                              sfcmd.log         
sfcm_nas_monitor.log  sfvs_ports.log
ff1000.log      ipmi_sel_current.log    ms_service.log  
sfapi_handler_service.log                                           
sfcmd_service.log  sffe_err.log          stonefly.log


Actual results:

Copy was executed as an atomic command and all files were copied in a bulk. 


Expected results:

Copy has to copy files one-by-one until the hard-limit quota is reached.
