ceph: Fix up after semantic merge conflict
The previous ceph-client merge resulted in ceph not even building, because there was a merge conflict that wasn't visible as an actual data conflict: commit 7221fe4c2ed7 ("ceph: add acl for cephfs") added support for POSIX ACL's into Ceph, but unluckily we also had the VFS tree change a lot of the POSIX ACL helper functions to be much more helpful to filesystems (see for example commits 2aeccbe957d0 "fs: add generic xattr_acl handlers", 5bf3258fd2ac "fs: make posix_acl_chmod more useful" and 37bc15392a23 "fs: make posix_acl_create more useful") The reason this conflict wasn't obvious was many-fold: because it was a semantic conflict rather than a data conflict, it wasn't visible in the git merge as a conflict. And because the VFS tree hadn't been in linux-next, people hadn't become aware of it that way. And because I was at jury duty this morning, I was using my laptop and as a result not doing constant "allmodconfig" builds. Anyway, this fixes the build and generally removes a fair chunk of the Ceph POSIX ACL support code, since the improved helpers seem to match really well for Ceph too. But I don't actually have any way to *test* the end result, and I was really hoping for some ACK's for this. Oh, well. Not compiling certainly doesn't make things easier to test, so I'm committing this without the acks after having waited for four hours... Plus it's what I would have done for the merge had I noticed the semantic conflict..
