vaapiencode: call ensure_encoder() at start()

Browse source 
Currently, specific encoder is created during set_format(). This might
lead to race condition when creating profiles with multiple encoders.

This patch moves ensure_encoder() call to start() vmethod to ensure
avoiding the race condition.
