Please try:

This bumps the scan beacon interval count from 1 to 4, just to try and
capture some more beacons during a scan.

(ie, if there's a beacon timer programmed, then we set it to wait for
4 beacon intervals and up to 100 milliseconds before going to the next
channel.)

I needed to do this in order for 5GHz SSIDs to properly show up in my
scan list once I was associated.

I've tested this on the 5100 (11abgn), 2300 (11bgn) and 6200 (11abgn).
I'll test others over the next few days.

Please test it out!
