[PATCH v2 1/3] gitweb: improve snapshot error handling

I reworded the message to be more specific about what code was
being changed.

--->8---
The last check in the second block of checks in the &git_snapshot
routine is never executed because the second last check is a superset
of the last check.

This change will switch the order of the last two checks. It has the
advantage of giving clients a more specific reason why they cannot get
a snapshot format if the format they have chosen is disabled.
