block: split blk_zone_update_request_bio into two functions

blk_zone_update_request_bio() does two things. First it checks if the
request to be completed was written via ZONE APPEND and if yes it then
updates the sector to the one that the data was written to.

This is small enough to be an inline function. But upcoming changes adding
a tracepoint don't work if the function is inlined.

Split the function into two, the first is blk_req_bio_is_zone_append()
checking if the sector needs to be updated. This can still be an inline
function. The second is blk_zone_append_update_request_bio() doing the
sector update.
