Interworking: Allow network block -based connection without ANQP matches 

Previously, network block -based connection could have been used to
override ANQP-based selection. However, if no ANQP-based matches were
present, no connection was started. Fix this by trying to connect if
any enabled network block has a match in the BSS table.
