The FUSE client process for a tiered volume crashes on concurrent attach-tier
and find operations

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


How reproducible:
Random but pretty common

Steps to Reproduce:
1. Create a distribute-replicate volume
2. Fuse mount the volume and untar a large file (I used a tar of the glusterfs
source code)
3. While the untar is in progress, attach a dist-rep hot tier or 4 bricks
4. Run find <mnt-path>


Actual results:
The FUSE client process will crash

Expected results:
The client process should not crash
