reiserfs: replace ll_rw_block()
ll_rw_block() is not safe for the sync read/write path because it cannot guarantee that submitting read/write IO if the buffer has been locked. We could get false positive EIO after wait_on_buffer() in read path if the buffer has been locked by others. So stop using ll_rw_block() in reiserfs. We also switch to new bh_readahead_batch() helper for the buffer array readahead path.
