Some drivers, in particular anything which creates an ifnet during
attach, need to have the current VNET set, as if_attach_internal() and
its callees access VNET-global variables.
device_probe_and_attach() handles this, but this is not the only way to
arrive in DEVICE_ATTACH. In particular, bus drivers may invoke
device_attach() directly, as does devctl2's DEV_ENABLE ioctl handler.
So, set the current VNET in device_attach() instead.
I believe it is always safe to use vnet0, as devctl2 ioctls are not
permitted within a jail.
