bcachefs: Fix race between btree updates & journal replay
Add a flag to indicate whether a journal replay key has been
overwritten, and set/test it with appropriate btree locks held.
This fixes a race between the allocator - invalidating buckets, and
doing btree updates - and journal replay, which before this patch could
clobber the allocator thread's update with an older version of the key
from the journal.
