fix(cgns): Fix int casting issue with ElementType_t enum

Compiler has the option of what type an enum is represented as.
When using a conditional (ternary) operator, the two operands will be
cast to the same type. The ElementType_t (which is strictly positive)
can be treated as a uint, which then causes the -1 value to be cast as
uint.
