matstack: Fix missing return on error. #41

It was caught by Travis running vet:

$ go tool vet ./
mgl32/matstack/matstack.go:27: result of errors.New call not used
mgl64/matstack/matstack.go:29: result of errors.New call not used

The command "go tool vet ./" exited with 1.

This fixes Travis build.
