NFS: Add support for AF_INET6 addresses in nfs_compare_super()

Refactor nfs_compare_super() and add AF_INET6 support.

Replace the generic memcmp() to document explicitly what parts of the
addresses must match in this check, and make the comparison independent
of the lengths of both addresses.

A side benefit is both tests are more computationally efficient than a
memcmp().
