net: atlantic: possible fault in transition to hibernation
during hibernation freeze, aq_nic_stop could be invoked
on a stopped device. That may cause panic on access to
not yet allocated vector/ring structures.
Add a check to stop device if it is not yet stopped.
Similiarly after freeze in hibernation thaw, aq_nic_start
could be invoked on a not initialized net device.
Result will be the same.
Add a check to start device if it is initialized.
In our case, this is the same as started.
