Bug 14868: (QA followup) Change permission check order

This patch changes the permission check order because haspermission
is the smaller check, and going through the patron/user and its guaranteed
before checking if it is (say) a staff member or even a superlibrarian doesn't
seem right.

Bonus: Remove unneeded C4::Auth import in Patron.pm
