qcacld-3.0: Fix implicit enum conversion in csr_fetch_valid_ch_lst

Fix implicit conversion from enumeration type 'tSirRFBand'
to different enumeration type 'eCsrBand'

Currently 3 different types of enums exist to enumerate the
band type.Remove eCsrBand and tSirRfBand and
use tSirRFBand everywhere.
