qca-wifi: Make the initialization of dfs->dfs_soc_obj unconditional

With the current implementation dfs->dfs_soc_obj was initialized in
function dfs_agile_soc_obj_init under the macro QCA_SUPPORT_AGILE_DFS
and ATH_SUPPORT_ZERO_CAC_DFS both of which are disabled for the low
memory profiles. Remove the initialization from here and unconditionally
initialize it in wlan_dfs_pdev_obj_create_notification.
