  [GStreamer] Avoid crash for unexisting pad in webkitGstTraceProcessingTimeForElement
https://bugs.webkit.org/show_bug.cgi?id=258986

Reviewed by Philippe Normand.

In some platforms srcPad can become null, hence crashing. Now it's protected.
We also avoid the cause of the crash in the first place.
