Subject: [PATCH] rndis_wlan: scanning, workaround device returning incorrect
 bssid-list item count.

Sometimes device returns wrong number of items in bssid-list. Appears that
some specific beacons trigger this problem and leads to very poor scanning
results. Workaround by ignoring num_items received from device and walkthrough
full bssid-list buffer.

v2: Fix buffer range checks and reading next item length. Old code read
    behind buffer on last item but didn't use those values as 'count' would
    also reach zero. Also fix resizing of buffer if device has larger buffer,
    old code assumed that BSSID-list OID would return same buffer size
    when it really can return yet another new larger length.
