libertas: disable functionality when interface is down

Browse Source 
Modify the driver so that it does not function when the interface is
down, in preparation for runtime power management.

No commands can be run while the interface is down, so the ndo_dev_stop
routine now directly does all necessary work (including asking the device
to disconnect from the network and disabling multicast functionality)
directly.

power_save and power_restore hooks are added meaning that card drivers
can take steps to turn the device off when the interface is down.

The MAC address can now only be changed when all interfaces are down;
the new address will be programmed when an interface gets brought up.
This matches mac80211 behaviour.

Also, some small cleanups/simplifications were made in the surrounding
device handling logic.
