The only difference in block_get_rq and block_bio was the last param
passed __entry->nr_sector & bio->bi_iter.bi_size respectively. Since
that is not the case anymore replace block_get_rq class with block_bio
for block_getrq and block_sleeprq events, also adjust the code to handle
null bio case in block_bio.
