media: amphion: reset instance if it's aborted before codec header parsed

[ Upstream commit 3984ea32e83bcad06b4b034ddd4b0a934c1b2f91 ]

there is hardware limitation that if it's aborted before
the first codec header parsed, the codec may be stalled
unless we do reset codec.

and drop the source change event if it's triggered after reset.
