x86/efi: Make efi_enter/leave_mm() use the use_/unuse_temporary_mm() machinery
This should be considerably more robust. It's also necessary for optimized
for_each_possible_lazymm_cpu() on x86 -- without this patch, EFI calls in
lazy context would remove the lazy mm from mm_cpumask().
[ mingo: Merged it on top of x86/alternatives ]
