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