[PATCH] Fix unconditional early exit in cg-fetch

From: Paolo 'Blaisorblade' Giarrusso <redacted>

When invoking cg-fetch, after fetching tags it exits here, probably for an
overlooked error handling (at least I corrected it this way).

This means, for instance, we exit without reporting the tag updates and without
removing the "fetch in progress" marker - leading to unconditional "Recovering
from interrupted fetch" at the very beginning with rsync transport. Indeed, this
is fixed by this patch.
