core: virtual devices can be available without a parent set

Browse Source 
When calling to nm_device_is_available, the device types that requires a
parent like VLAN or MACVLAN checks that their parent exists.

nm_device_is_available is a function to check if the device is available
to activate a connection, so it makes sense that if the parent is not
present it can't be activated.

However, this is wrong for 2 reasons:
1. Most of they are virtual devices that might be unrealized when
   checking its availability. If they're unrealized, their parent hasn't
   been set yet.
2. Even if they're realized, their current parent might not be the one
   that is defined in the connection that is being activated.

This is causing that unrealized devices are not being activated as ports
because nm_manager_get_best_device_for_connection thinks that they are
not available.

Get rid of these checks for the parent in the is_available callbacks.

Fixes: ba86c208e0 ('Revert "core: prevent the activation of unavailable OVS interfaces only"')
Fixes: 774badb151 ('core: prevent the activation of unavailable devices')
