Subject: [PATCH] Bug 29840: Deal with non-existing biblionumber in
 opac-reserve

We should not explode if the biblionumber passed in not in DB.

Test plan:
Hit /cgi-bin/koha/opac-reserve.pl?biblionumber=42424
and notice the error message.

Without this patch you got
Can't call method "holds" on an undefined value at /kohadevbox/koha/opac/opac-reserve.pl line 172
