team: Fix feature exposure when no ports are present

Browse Source 
Small follow-up to align this to an equivalent behavior as the bond driver.
The change in 3625920b62 ("teaming: fix vlan_features computing") removed
the netdevice vlan_features when there is no team port attached, yet it
leaves the full set of enc_features intact.

Instead, leave the default features as pre 3625920b62, and recompute once
we do have ports attached. Also, similarly as in bonding case, call the
netdev_base_features() helper on the enc_features.
