qcacmn: Make init of dfs->dfs_soc_obj independent of the macros

With the current implementation dfs->dfs_soc_object 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. Hence the dfs->dfs_soc_obj was not initialized for these
profiles, this led to a crash when the following access was made in
dfs_is_true_160mhz_supported and dfs_is_restricted_80p80mhz_supported.

psoc = dfs->dfs_soc_obj->psoc
Fix this by unconditionally initializing the dfs->dfs_soc_obj in
wlan_dfs_pdev_obj_create_notification.
