zhangyi (F) 3a53d012bd jbd2: abort journal if free a async write error metadata buffer
[ Upstream commit c044f3d836 ]

If we free a metadata buffer which has been failed to async write out
in the background, the jbd2 checkpoint procedure will not detect this
failure in jbd2_log_do_checkpoint(), so it may lead to filesystem
inconsistency after cleanup journal tail. This patch abort the journal
if free a buffer has write_io_error flag to prevent potential further
inconsistency.
