    nfs: prevent logging missing 'system.posix_acl_*' xattrs

    The nfs.log gets spammed with messages that the system.posix_acl_access
    and system.posix_acl_default xattrs are not set. The logging happens
    because the dictionary that contains the xattrs is empty/NULL in case
    the getxattr() did not return any contents for the ACLs.
