Jouni Malinen fce6ddd8d0 tests: Avoid unnecessary wlantest failures
It is possible that wlantest has not yet created the BSS entry in all
cases, so interpret failures (no BSS entry being the most likely cause)
as zero counters. Similarly, ignore clear_bss_counters errors since they
are most likely reporting that the BSS was not found and as such, there
was no need to clear the counters anyway.
