From: Luciano Coelho <luciano.coelho@xxxxxxxxx>
The only difference in the ssid_bitmap between LMAC and UMAC scans is
that in LMAC bits 1 to 20 are used, while in UMAC bits 0 to 19 are
used (*sigh*). So we can combine the bitmap creation into a single
function and simply shift left if LMAC is used.
