device: explicitly handle unrealized devices in is_available()

Browse source 
Unrealized software devices are always available for activation,
hardware devices never.

In nm_manager_get_best_device_for_activation() we call
nm_device_is_available() on candidate devices. Without this fix, any
unrealized software device would be not considered ready for
activation, which is wrong.

A software device can override the default implementation of
is_available(). For example NMDeviceOvsInterface does that and only
checks the OVSDB is ready.

Fixes: ba86c208e0 ('Revert "core: prevent the activation of unavailable OVS interfaces only"')
