ocfs2: fix NULL pointer dereference in function ocfs2_abort_trigger()
ocfs2_abort_trigger() use bh->b_assoc_map to get sb. But there's no
function to set bh->b_assoc_map in ocfs2, it will trigger NULL pointer
dereference while calling this function. We can get sb from
bh->b_bdev->bd_super instead of b_assoc_map.
