fftools/opt_common: check the return value of av_hwdevice_get_type_name before printing it
It may be NULL, as is the case for D3D11VA_VLD. Running "ffmpeg -h decoder=h264" on a Windows build Before: Decoder h264 [H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10]: Supported hardware devices: dxva2 (null) d3d11va cuda After: Decoder h264 [H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10]: Supported hardware devices: dxva2 d3d11va cuda Signed-off-by: James Almer <jamrial@gmail.com>
