bcachefs: Correctly order flushes and journal writes on multi device filesystems
All writes prior to a journal write need to be flushed before the
journal write itself happens. On single device filesystems, it suffices
to mark the write with REQ_PREFLUSH|REQ_FUA, but on multi device
filesystems we need to issue flushes to every device - and wait for them
to complete - before issuing the journal writes. Previously, we were
issuing flushes to every device, but we weren't waiting for them to
complete before issuing the journal writes.
