[fidl][go] Fix for case of too few handles

This fixes failures in OptionalXUnionInStructPresentInvalidNumHandles
in Ic5b2a8b9642b2a5519d97d02ad6a3f92a343e2a9 due to a handle being
read when no handles are specified.

In this fix, the unmarshaler defers validating the number of handles
to the inner decoder. This keeps the same ordering of errors as
before and avoids multiple checks for the same error.
