Borislav Petkov a07de9b98f x86/microcode: Fix the ancient deprecated microcode loading method 
[ Upstream commit 24613a04ad ]

Commit

  2613f36ed9 ("x86/microcode: Attempt late loading only when new microcode is present")

added the new define UCODE_NEW to denote that an update should happen
only when newer microcode (than installed on the system) has been found.

But it missed adjusting that for the old /dev/cpu/microcode loading
interface. Fix it.

Fixes: 2613f36ed9 ("x86/microcode: Attempt late loading only when new microcode is present")
