These can be trivially open coded in the callers.

It is not necessary since it is set later just before function
return success.

Just print the block device name directly using the %pg format specifier.

Only the priv field of rnbd_dev_blk_io is used, so store the value of
that in bio->bi_private directly and remove the entire bio_set overhead.

The memory mapped in process_rdma is contiguous, so there is no need
to loop over bio_add_page. Remove rnbd_bio_map_kern and just open code
the bio allocation and mapping in the caller.

Since we always set bi_end_io after call rnbd_bio_map_kern, so the
setting in rnbd_bio_map_kern is redundant.

The function only has one caller, so let's open code it in process_rdma.
Another bonus is we can avoid push/pop stack, since we need to pass 8
arguments to rnbd_dev_submit_io.

This provides helper functions for IO submitting to block dev.
