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.)
