This patch fixes a bug in which function gfs2_log_flush can get into an infinite loop when a gfs2 file system is withdrawn. The problem is the infinite loop "for (;;)" in gfs2_log_flush which would never finish because the io error and subsequent withdraw prevented the items from being taken off the ail list.
This patch tries to clean up the mess by allowing withdraw situations to move not-in-flight buffer_heads to the ail2 list, where they will be dealt with later.
