commit-reach: avoid NULL dereference

The loop at the top of can_all_from_reach_with_flag() already
accounts for `from->objects[i].item' being NULL, so it follows
the cleanup loop should also account for a NULL `from_one'.

I managed to segfault here on one of my giant, many-remote repos
using `git fetch --negotiation-tip=...  --negotiation-only'
where the --negotiation-tip= argument was a glob which (inadvertently)
captured more refs than I wanted.  I have not reproduced this
in a standalone test case.
