It was possible for regulatory domain changes to "leak" into following test cases in number of cases where the cfg80211 BSS table remained after regulatory domain had been restored to world roaming. Try to make this less likely to occur by explicitly clearing BSS table at the end of test cases that use different regulatory domain. This makes P2P test cases that verify channel selection based on world roaming rules more robust. Signed-off-by: Jouni Malinen <j@w1.fi>
