net: fix check for number of parameters to -netdev socket

Since commit 0f8c289ad "net: fix -netdev socket,fd= for UDP sockets"
we allow more than one parameter for -netdev socket. But now
we run into an assert when no parameter at all is specified

> qemu-system-x86_64 -netdev socket
socket.c:729: net_init_socket: Assertion `sock->has_udp' failed.

Fix this by reverting the change of the if condition done in 0f8c289ad.
