Jouni Malinen 468efe79a7 tests: Work around exception handling issue in wpas_config_file 
Raising an exception while the wlan5 interface was remove (i.e., between
wpas.interface_remove() and .interface_add() calls) would result in the
cleanup code failing and generating yet another exception while the
first one was being processed. Work around this by re-adding the wlan5
interface back temporarily if the interface is not available for the
cleanup operations.
