mesa: glGet: simplify the 'enum not found' condition

When traversing the hash table looking up an enum that is invalid we
eventually reach the first element in the descriptor array. By looking
at the type of that element, which is always TYPE_API_MASK, we know that
we can stop the search and return error. Since this element is always
the first it's enough to check for its index being 0 without looking at
its type.

Later in this patchset, when we generate the hash tables during build
time, this will allow us to remove the TYPE_API_MASK and related flags
completly.
