qcacmn: Fix null pointer dereference, wlan_cp_stats_psoc_obj_create_handler

In wlan_cp_stats_psoc_obj_create_handler() multiple error paths
lead to label wlan_cp_stats_psoc_obj_create_handler_return.

In the label, posc_cs is not null checked before passing to the
csc->cp_stats_psoc_obj_deinit() causing NULL pointer dereference.
