[PATCHv2 4/5] efi_mem_sort: skip unnecessary compare

[<rs@ti.com>]

From: Randolph Sapp <rs@ti.com>

I don't want to think about the possibility of this pointer containing a
reference to something from a previous iteration. At best it results in
a some arithmetic and a comparison that should usually be unnecessary.
