[Qemu-trivial] [PULL 1/8] slirp: Give error message if hostfwd_add/remove for unrecognized vlan/stack

[Michael Tokarev]

From: Peter Maydell <address@hidden>

If the user specified a (vlan ID, slirp stack name) tuple in a monitor
hostfwd_add/remove command and we can't find it, give the user an
error message rather than silently doing nothing.

This brings this error case in slirp_lookup() into line with the
other two.
