selinux: align avc_has_perm_noaudit() prototype with definition

A trivial correction to convert an 'unsigned' parameter into an
'unsigned int' parameter so the prototype matches the function
definition.

I really thought that someone submitted a patch for this a few years
ago but sadly I can't find it now.
