bnxt_en: Prevent kernel panic when receiving unexpected PHC_UPDATE event
The firmware can send PHC_RTC_UPDATE async event on a PF that may not have PTP registered. In such a case, there will be a null pointer deference for bp->ptp_cfg when we try to handle the event. Fix it by not registering for this event with the firmware if !bp->ptp_cfg. Also, check that bp->ptp_cfg is valid before proceeding when we receive the event.
