[][MAC80211][hostapd][Fix hostapd_dfs_start_cac log]

[Description]
Fix hostapd_dfs_start_cac log
1. seg0 should be channel instead of cf1
2. The type of chan_width in hostapd_dfs_start_cac is "enum chan_width"
However, the type of width in other functions are "enum oper_chan_width".
So, change it to real bandwidth size (in MHz) to avoid misleading log.

[Release-log]
N/A
