try to get IP of VM only when its state is Running

for crc status command to get the status of the OpenShift
cluster we need the IP address of the VM but while  using
network-mode 'system' and a Stopped VM this fails with:
Error getting ip: host is not running

this checks if the VM is in Running state before trying to
get the VM IP

we do not the see the same error for 'user'  network-mode
as in that case the VM ip is always 127.0.0.1
