qcacmn: Fix wrong MLO 2 GHz link CCFS1 in response to get_channel

2 GHz link CCFS may not filled correctly in vht/he op, wrong CCFS0
is got from util_scan_sec_chan_freq_from_htinfo and passed to kernel,
regulatory check failed, disconnect will happen.

To fix it, add new API util_scan_ccfs0_from_htinfo, and get CCFS0 by it.
