x86/vmi: fix interrupt enable/disable/save/restore calling convention.

Zach says:
> Enable/Disable have no clobbers at all.
> Save clobbers only return value, %eax
> Restore also clobbers nothing.

This is precisely compatible with the calling convention, so we can
just call them directly without wrapping.

(Compile tested only.)
