drm/udl: Return error if vendor descriptor is too short

Browse source

There need to be least 5 bytes in the vendor descriptor. Return
an error otherwise. Also change the branching to early-out on
the error. Adjust indention of the rest of the parser function.

The original length test expected more than 5 bytes in the vendor
descriptor. As a descriptor with no key-value pairs has exactly 5
bytes and is still valid, change the test to accept this case as
well.
