AP_GPS: Fix a bound error when calculating GNSS minimum channels.

Browse Source 
This is really just calculating the hamming weight of the GNSS_MODE bitmask, but I don't know if the APM compiler could handle the GCC intrinsic that could calculate it faster, and this is done so rarely there isn't a significant penalty to using the for loop.
