icnss: Trigger recovery only if PDR enabled



To trigger WLAN host initiated WLAN FW recovery, platform driver
needs to have service notifier handle. Service notifier handle is
obtained only when service locator locates the WLAN user PD. If
service locator doesn't locate the WLAN user PD then service
notifier handle can be NULL. Add sanity check to make sure PDR is
enabled in platform driver before triggering PD restart.
