qcacmn: Set dfs_set_cfreq2 with correct DFS flag

In MCL code, QCA_DFS_NOL_OFFLOAD is no defined,
which causes the utils_is_dfs_cfreq2_ch always return
"false".
In function vdev_mgr_start_param_update
the "dfs_set_cfreq2" needs to be set correct dfs flag from
utils_is_dfs_cfreq2_ch so that vdev start wmi command will include
correct DFS flag - WMI_CHAN_FLAG_DFS_CFREQ2 for AP home channel.

Move utils_is_dfs_cfreq2_ch function out of WLAN_DFS_FULL_OFFLOAD
and QCA_DFS_NOL_OFFLOAD build flag.
