x86: EFI: fix use of unitialized variable and the cache logic
Andi Kleen pointed out that the cache attribute logic is reverse in
efi_enter_virtual_mode(). This problem alone is harmless as we do not
(yet) do cache attribute conflict resolution. (This bug was not present
in the original EFI submission - I introduced it while fixing up rejects.)
While reviewing this code I noticed a second, worse problem: the use of
uninitialized md->virt_addr.
Fix both problems.
