video: Getting component offsets without dimensions is fine if it is not YUV

This fixes a regression that an assertion would happen if
gst_video_get_component_offset would be called with width or
height as 0.

Calling it with 0 is fine if the format isn't yuv and this
was already being used in some other places of video.c
