cifs: fix hardcoded default security descriptor length
It was hardcoded to 192 bytes, which was not enough when the max number of subauthorities went to 15. Redefine this constant in terms of sizeof the structs involved, and rename it for better clarity. While we're at it, remove a couple more unused constants from cifsacl.h.
