qcacmn: Handle return status when IPA UC not loaded

Currently if IPA UC is not loaded when opt wifi dp
is enabled, the return status is not handled correctly.
This causes the qdf_event_create to happen for ipa ctx
which later triggers an assert during ipa cleanup.
This fix will handle this scenario.
