Martin Storsjö 0aa77d2985 Remove a duplicated field in SWelsSvcCodingParam 
The same field already exists in SEncParamExt. When the
initialization was deduplicated in ac404ce, this lead to
reading the now uninitialized field in SWelsSvcCodingParam,
instead of the properly initialized one in the base class.
