Latchesar Ionkov c959df9f01 v9fs: don't use primary fid when removing file
v9fs_insert uses v9fs_fid_lookup (which also locks the fid) to get the
primary fid associated with the dentry and destroys the v9fs_fid struct
after removing the file.  If another process called v9fs_fid_lookup on the
same dentry, it may wait undefinitely for the fid's lock (as the struct is
freed).

This patch changes v9fs_remove to use a cloned fid, so the primary fid is
not locked and freed.
