H A Dblockdev-nbd.ca5fced40 Thu May 12 00:49:23 GMT 2022 Eric Blake <eblake@redhat.com> qemu-nbd: Pass max connections to blockdev layer

The next patch wants to adjust whether the NBD server code advertises
MULTI_CONN based on whether it is known if the server limits to
exactly one client. For a server started by QMP, this information is
obtained through nbd_server_start (which can support more than one
export); but for qemu-nbd (which supports exactly one export), it is
controlled only by the command-line option -e/--shared. Since we
already have a hook function used by qemu-nbd, it's easiest to just
alter its signature to fit our needs.
