lavc: set frame parameters after decoding only if necessary
...
Direct rendering capable decoders call get_buffer() which will set the
frame parameters.
Prevents frames with wrong parameters when a decoder outputs delayed
frames after a resolution or pixel format change.

Some invocations include a verb in the log message, others do not. Yet

function invocations.
