bcachefs: Fix incorrect state count 



atomic64_read(&j->seq) - j->seq_write_started == JOURNAL_STATE_BUF_NR is
the condition in journal_entry_open where we return JOURNAL_ERR_max_open,
so journal_cur_seq(j) - seq == JOURNAL_STATE_BUF_NR means that the buf
corresponding to seq has started to write.
