From: Paolo Bonzini <pbonzini@redhat.com>

"netdev_add help" is causing QEMU to exit because the code that

invokes show_netdevs is shared between CLI and HMP processing.

Move the check to the callers so that exit(0) remains only

in the CLI flow.

"netdev_add help" is not fixed by this patch; that is left for

later work.
