qcacmn: Fix null scan object dereference in ucfg
Currently, ucfg_scan_register_pno_cb and ucfg_scan_get_scan_id
do not do null validation for scan object which can lead to null
pointer dereference. wlan_psoc_get_scan_obj_fl returns null in case
of invalid component id or null psoc and that null scan object is
dereferenced due to missing null validation.
Add null pointer check for scan object in ucfg_scan_register_pno_cb
and ucfg_scan_get_scan_id. Return zero scan id from ucfg_scan_get_scan_id
in case of null scan object.
