Subject: [PATCH] media: venus: keep resolution when adjusting format

When checking a format for validity, the resolution is reset to 1280x720
whenever the pixel format is not supported. This behavior can mislead
user-space into believing that this is the only resolution supported,
and looks strange considering that if we try/set the same format with
just the pixel format changed to a valid one, the call will this time
succeed without altering the resolution.

Resolution is managed independently of the pixel format, so remove this
reset.
