cpu/x86/smm/smmhandler: Fix x86_64 assembly exit
Fix an issue the assembler didn't warn about to fix a crash on real
hardware. qemu didn't catch this issue either.
The linker uses the same address for variables in BSS if they aren't
initialized in the code. This results in %edx being set to the value
of %eax, which causes an exception restoring IA32_EFER on real
hardware.
Tested on qemu with KVM enabled.
