[PATCH] hmp: Changed hmp_netdev_add() using qmp_marshal_netdev_add()

[andrew@daynix.com]

From: Andrew Melnychenko <andrew@daynix.com>

There is an issue, that netdev can't be removed if it was added using hmp.
The bug appears after 08712fcb851034228b61f75bd922863a984a4f60 commit.
It happens because of unclear QemuOpts that was created during
hmp_netdev_add(), now it uses qmp analog function -
qmp_marshal_netdev_add().
