Callers of __jbd2_journal_unfile_buffer() and __jbd2_journal_refile_buffer() assume that the b_transaction is set. In fact if it's not, we can end up with journal_head refcounting errors leading to crash much later that might be very hard to track down. Add asserts to make sure that is the case. We also make sure that b_next_transaction is NULL in __jbd2_journal_unfile_buffer() since the callers expect that as well and we should not get into that stage in this state anyway, leading to problems later on if we do. Tested with fstests.
