selinux: Print 'sclass' as string when unrecognized netlink message occurs

commit cded3fffbeab777e6ad2ec05d4a3b62c5caca0f3 upstream.

This prints the 'sclass' field as string instead of index in unrecognized netlink message.
The textual representation makes it easier to distinguish the right class.
