Prevent send-pack from segfaulting (backport from 'master')

Browse Source 
4491e62ae9 (Prevent send-pack from
segfaulting when a branch doesn't match) is hereby cherry-picked
back to 'maint'.

If we can't find a source match, and we have no destination, we
need to abort the match function early before we try to match
the destination against the remote.
