4.14-stable review patch. If anyone has any objections, please let me know.

commit 24568b47d48ec8c906fd0f589489a08b17e1edca upstream.
It turns out OSXSAVE needs to be checked only for AVX, not for SSE. Without this patch the affected modules refuse to load on CPUs with SSE2 but without AVX support.
