tests: Avoid failure in IBSS testing due to old scan results

ibss_open_fixed_bssid could leave behind old BSS entries that would
survive to the next test case. ibss_vht_80p80 would fail to establish
the IBSS on the expected channel in such cases. Explicitly flush the BSS
entries from kernel to avoid this.
