nfsd4: Fix filp leak
23fcf2ec93fb8573a653408316af599939ff9a8e (nfsd4: fix oops on lock failure)
The above patch breaks free path for stp->st_file. If stp was inserted
into sop->so_stateids, we have to free stp->st_file refcount. Because
stp->st_file refcount itself is taken whether or not any refcounts are
taken on the stp->st_file->fi_fds[].
