ac10a9611d bcachefs: Some fixes for building in userspace
userspace allocators don't align allocations as nicely as kernel
allocators, which meant that in some cases we weren't allocating big
enough bvec arrays - just make the calculations more rigorous and
explicit to fix it.

9c859dc91b bcachefs: Assorted journal refactoring
Also improve error reporting - only return an error from
bch2_journal_flush_seq() if we had an error writing that entry (i.e. not
if there was an error with a newer entry).

c692399529 bcachefs: don't call bch2_bucket_seq_cleanup from journal_buf_switch
journal_buf_switch is called from the foreground when getting a journal
reservation and thus is somewhat latency sensitive;
bch2_bucket_seq_cleanup has to run infrequently but is a bit expensive
when it does run.

Call it from the journal write path instead, and punt the journal write
to worqueue context.
