David HowellsandGreg Kroah-Hartman 81b048b948 cachefiles: Fix non-taking of sb_writers around set/removexattr ...

[ Upstream commit 80887f3167 ]

Unlike other vfs_xxxx() calls, vfs_setxattr() and vfs_removexattr() don't
take the sb_writers lock, so the caller should do it for them.

Fix cachefiles to do this.
