s3:smbd:vfs_acl: fix a PANIC when setting an ACL fails with ACCESS_DENIED

Omission to free the talloc frame causes a panic (at least in developer mode)
in the next main event loop due to "Frame not freed in order."
(Freed frame ../source3/smbd/process.c:3617, expected ../source3/modules/vfs_acl_common.c:534.)
