Instead of dying there, let the caller high up in the callchain
notice the error and handle it (by dying, still).
There are two call sites of read_and_refresh_cache(), one of which is
pick_commits(), whose callers were already prepared to do the right
thing given an "error" return from it by an earlier patch, so the
conversion is safe.
The other one, sequencer_pick_revisions() was also prepared to relay
an error return back to its caller in all remaining cases in an
earlier patch.
