EFI: free unused boot mem in at least some cases
Address at least the primary reason why 52bba67f8b87 ("efi/boot: Don't
free ebmalloc area at all") was put in place: Make xen_in_range() aware
of the freed range. This is in particular relevant for EFI-enabled
builds not actually running on EFI, as the entire range will be unused
in this case.
