Commit b8a7a3a6 change get_acl() for posix xattr to always cache
the ACL which increases the reference count. That reference count
can be reduced by have ll_get_acl() call forget_cached_acl() which
it wasn't. When an inode gets deleted by Lustre the POSIX ACL
reference count is tested to ensure its 1 and if not produces an error.
Since forget_cached_acl() was not called Lustre started to complain.
This patch changes ll_get_acl() to call forget_cached_acl().
