iwlwifi: iwlagn_request_scan: Fix check for priv->scan_request ...
The WARN_ON_ONCE() check for scan_request will not correctly detect
a NULL pointer for scan_type == IWL_SCAN_NORMAL. Make it explicit
that the check only applies to normal scans.
Convert WARN_ON_ONCE to WARN_ON since priv->scan_request really _can't_
be NULL for normal scans. If it is then we should emit frequent warnings.
This smatch warning led to scrutiny of iwlagn_request_scan():
drivers/net/wireless/iwlwifi/dvm/scan.c:894 iwlagn_request_scan() error: we previously assumed 'priv->scan_request' could be null (see line 792)
