gitweb: improve snapshot error handling

Browse source 
The last check in the second block of checks in the &git_snapshot routine
is never executed because the second to last check is a superset of the
last check.

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.
