Linux 4.8 compat: posix_acl_valid()

Browse Source 
The posix_acl_valid() function has been updated to require a
user namespace.  Filesystem callers should normally provide the
user_ns from the super block associcated with the ACL; the
zpl_posix_acl_valid() wrapper has been added for this purpose.
See https://github.com/torvalds/linux/commit/0d4d717f for
complete details.
