x86: fix warning in e820_reserve_resources with 32bit

Browse source

when 64bit resource is not enabled, we get:

arch/x86/kernel/e820.c: In function ‘e820_reserve_resources’:
arch/x86/kernel/e820.c:1217: warning: comparison is always false due to limited range of data type

because res->start/end is resource_t aka u32. it will overflow.

fix it with temp end of u64
