rnbd-srv: Fix server side setting of bi_size for special IOs

Browse source

[ Upstream commit 4ac9690d4b ]

On rnbd-srv, the bi_size of the bio is set during the bio_add_page
function, to which datalen is passed. But for special IOs like DISCARD
and WRITE_ZEROES, datalen is 0, since there is no data to write. For
these special IOs, use the bi_size of the rnbd_msg_io.
