[PATCH] efistub/x86: Use struct boot_e820_entry for size calculations

[Thorsten Blum <blum@kernel.org>]

alloc_e820ext() and setup_e820() use sizeof(struct e820_entry) when
calculating the sizes of boot_e820_entry structures.

Even though struct e820_entry and struct boot_e820_entry have the same
size, use sizeof(struct boot_e820_entry) for consistency instead.
