qcacld-3.0: Modify bitmap to band conversion algorithm for advance logs

In the api wlan_convert_bitmap_to_band(), the bitmap
to band conversion algorithm evaluate 1st bit in the
bitmap as 2.4 GHz link instead of 0th bit.

Modify the bitmap to band conversion algorithm to
evaluate 0th bit for 2.4 GHz band instead of 1st
bit of the band bitmap received from FW.
