The trusted.pgfid will be created by the next name lookup; nameless lookup 
don't create it.

Restarting glusterfsd here cleanup all inode cache from memory;
after starting, inode of testfile92's parent is NULL.

Because, nfs-ganesha and nfs client has cache for testfile92,
before write fops, no name lookup happens that trusted.pgfid is not created for 
testfile92.

Quota_writev call quota_build_ancestry building the ancestry in 
quota_check_limit,
but testfile92 doesn't contain trusted.pgfid, so that write fops failed with 
Invalid argument.

I have no idea of fixing this problem, any comments are welcome.
