[PATCH 6/7] netlist.py: remove the forth 'None' return in get_network_selection()

[Daniel Henrique Barboza]

Commit v2.2.1-200-g4c3c53f7 ("virtManager: Remove network portgroup
UI") removed 'portgroup', the forth value of the returned tuple in
get_network_selection(), and all related code that was using this
forth value.

That change forgot to change the line where, if no rows are found, a
tuple with "None" values is returned. The "None" tuple is still
returning 4 "None" values. Since no remaining code is checking for
a forth value, this is benign and has no impact in the logic.

'pylint' does not seem to care though, and it is complaining about
'unbalanced-tuple-unpacking' because, in the condition mentioned above,
a forth "None" value is returned and no one is bothering checking for
it.
