Avoid beyond bounds copy while caching ACL
commit 5794d21ef4639f0e33440927bb903f9598c21e92 upstream.
When attempting to cache ACLs returned from the server, if the bitmap
size + the ACL size is greater than a PAGE_SIZE but the ACL size itself
is smaller than a PAGE_SIZE, we can read past the buffer page boundary.
