Subject: [PATCH] x86, e820: Clean up sanitize_e820_map() users

The argument 3 of sanitize_e820_map() will only be updated upon a
successful sanitization. Some of the callers have extra conditionals
for the same purpose. Clean them up.

default_machine_specific_memory_setup() must keep the extra
conditional because boot_params.e820_entries is an u8 and not an u32,
so the direct update would overwrite other fields in boot_params.
