[PATCH 2/9] tests: Wait for scan to complete on all interfaces in reset()

[Ilan Peer]

From: Andrei Otcheretianski <andrei.otcheretianski at intel.com>

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., P2P_FIND. This might affect
subsequent tests.

Fix this by waiting until the scan is done both on wlanX and P2P
Device interfaces.
