io_uring/net: use struct io_br_sel->val as the send finish value

Currently a pointer is passed in to the 'ret' in the send mshot handler,
but since we already have a value field in io_br_sel, just use that.
This is also in preparation for needing to pass in struct io_br_sel
to io_send_finish() anyway.
