lkdtm: replace ll_rw_block with submit_bh
Function ll_rw_block was removed in commit 79f597842069 ("fs/buffer: remove ll_rw_block() helper"). There is no unified function to sumbit read or write buffer in block layer for now. Consider similar sematics, we can choose submit_bh() to replace ll_rw_block() as predefined crash point. In submit_bh(), it also takes read or write flag as the first argument and invoke submit_bio() to submit I/O request to block layer.
