Subject: nbd/client: fix nbd_send_request to return int
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=490dc5ed9bfbaf50ed8186c9729a81f530a11188;p=qemu.git

nbd/client: fix nbd_send_request to return int

Fix nbd_send_request to return int, as it returns a return value
of nbd_write (which is int), and the only user of nbd_send_request's
return value (nbd_co_send_request) consider it as int too.
