refs #24010, refs https://github.com/nim-lang/Nim/issues/24125#issuecomment-2358377076 The generic mismatch errors added in #24010 made it possible for `nArg` to be `nil` in the error reporting since it checked the call argument list, not the generic parameter list for the mismatching argument node, which causes a segfault. This is fixed by checking the generic parameter list immediately on any generic mismatch error. Also the `typedesc` type is skipped for the value of the generic params since it's redundant and the generic parameter constraints don't have it.
