[PATCH] tmpfs: Decrement i_nlink correctly in shmem_rmdir()

[Hugh Dickins <hugh@veritas.com>]

From: Sergey Vlasov <vsu@altlinux.ru>

shmem_rmdir() must undo the increment of i_nlink done in
shmem_get_inode() for directories, otherwise at least
IN_DELETE_SELF inotify event generation is broken.

This can also be included in 2.6.17, though only inotify depends on it.
