Commit 53606b105c ('tests: Wait for scan
to complete on all interfaces in reset()') added option of passing
ifname to get_driver_status(). This could result in FAIL-NO-IFNAME-MATCH
returns that get printed out in "Ignore unexpected status-driver line"
messages if the interface is not found. Check for this case to avoid

When WpaSupplicant executes reset() it waits until all the ongoing scans
are completed. However, it checks the status of the wlanX interface
only. If a dedicated P2P device interface is used, scan may be still
running on the P2P Device interface, e.g., due to P2P_FIND. This might
affect subsequent tests.
Fix this by waiting until the scan is done both on wlanX and P2P
Device interfaces.
