gve: Fix use of netif_carrier_ok()
GVE driver wrongly relies on netif_carrier_ok() to check the
interface administrative state when resources are being
allocated/deallocated for queue(s). netif_carrier_ok() needs
to be replaced with netif_running() for all such cases.
Administrative state is the result of "ip link set dev <dev>
up/down". It reflects whether the administrator wants to use
the device for traffic and the corresponding resources have
been allocated.
Fixes: 5f08cd3d6423 ("gve: Alloc before freeing when adjusting queues")
