core: prevent the activation of unavailable OVS interfaces only

Browse Source 
Preventing the activation of unavailable devices for all device types is
too aggresive and leads to race conditions, e.g when a non-virtual bond
port gets a carrier, preventing the device to be a good candidate for
the connection.

Instead, enforce this check only on OVS interfaces as NetworkManager
just makes sure that ovsdb->ready is set to TRUE.
