softworkz edd28770be avcodec/dvbsubdec: Fix conditions for fallback to default resolution ...

The previous code expected a segment of type CLUT definition to exist
in order to accept a set of segments to be complete.
This was an incorrect assumption as the presence of a CLUT segment
is not mandatory.
(version 1.6.1 of the spec is probably a bit more clear about this
than earlier versions: https://www.etsi.org/deliver/etsi_en/
300700_300799/300743/01.06.01_20/en_300743v010601a.pdf)

The incorrect condition prevented proper fallback to using the default
resolution for the decoding context.

This also adds variables and moves the fallback check to the outside
for better clarity.
