Luis Henriques (SUSE) 972090651e ext4: fix incorrect tid assumption in __jbd2_log_wait_for_space()
Function __jbd2_log_wait_for_space() assumes that '0' is not a valid value
for transaction IDs, which is incorrect.  Don't assume that and invoke
jbd2_log_wait_commit() if the journal had a committing transaction instead.
