qcacmn: Add frequency range check in reg_get_band_cap_from_op_class

Browse Source 
When the operating class 82 is given as an input to the function
reg_get_band_cap_from_op_class, it is not found due to an
incorrect conditional logic that checks the starting frequency of a
band.

To address this problem, add a function
reg_get_band_cap_from_chan_set and call it within the function
reg_get_band_cap_from_op_class, to check if a channel in the channel
set, is within the frequency range of the band.
