Description of problem:
in some of the fd based operations (like ftruncate(),fsetxattr() etc), 'marker_inode_loc_fill()' is called in maker.c, which may fail in case the entry is unlink()'d already, thus actually failing the FOP, which otherwise passes successfully.

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

How reproducible:
have a .c code which does these operations in order, "fd=open(file), unlink(file), ftruncate(fd,0)", without quota enabled, it passes fine, where as with quota it fails.

Steps to Reproduce:
1.as explained above
  
Actual results: with quota ftruncate fails with ENOMEM

Expected results: with or without quota ftruncate() should pass through
