qcacld-3.0: Set correct center frequency for bandwidth 160 MHz

Currently center frequency pass to API to check unsafe channel is
not correct set for bandwidth greater than 80 MHz. It lead to
unexpected shrink bandwidth.

For channel bandwidth greater than 80 MHz, center frequency should
set to mhz_freq_seg1 instead of mhz_freq_seg0.
