4881fdb756 bcachefs: initial gc no longer needs to touch every node

1dd7f9d98d bcachefs: Rewrite journal_seq_blacklist machinery 
Now, we store blacklisted journal sequence numbers in the superblock,
not the journal: this helps to greatly simplify the code, and more
importantly it's now implemented in a way that doesn't require all btree
nodes to be visited before starting the journal - instead, we
unconditionally blacklist the next 4 journal sequence numbers after an
unclean shutdown.

so we have to try writing again after they've been flushed.
