decodebin3: Add missing INPUT_LOCK() before ensure_input_parsebin()

Browse source 
ensure_input_parsebin() has a top comment saying it must be called with
INPUT_LOCK taken, but 2 out of 3 usages of the function call it without
taking that mutex.

This patch adds locking in these two remaining usages.
