Bug 40866: Remove unused $message variable from circulation

The $message variable was declared in circ/circulation.pl but never
actually set, making the "No patron matched" template block unreachable.

This is a remnant from old code that was incompletely cleaned when that
functionality was changed/removed.

This patch removes the unused variable, template parameter, and the
unreachable template block.
