GCE: Enable vtnet(4) Multiqueue.
Removes hw.vtnet.mq_disable=1.
This workaround was originally introduced nearly a decade ago to
address stability issues on KVM that have long since been resolved
in both the FreeBSD driver and the GCE hypervisor. Removing this
allows network interrupts to scale across multiple vCPUs.
Tested on n2-highcpu-16 VM with 15.0-RELEASE and confirmed multiple
queue pairs active and interrupts handling across cores.
