Add logging of DXVAVDA errors with line numbers.

Add logging of DXVAVDA errors with line numbers.

This will help us track down the causes of video decoding errors in
about:gpu and on the GPU bots.

Logging only the line number should help prevent code bloat due to
logging strings (and code) in release builds, and should make it easy
to identify exactly what code failed.
