mm/memblock.c: avoid abuse of RED_INACTIVE
RED_INACTIVE is a slab thing, and reusing it for memblock was
inappropriate, because memblock is dealing with phys_addr_t's which have a
Kconfigurable sizeof().
Create a new poison type for this application. Fixes the sparse warning
warning: cast truncates bits from constant value (9f911029d74e35b becomes 9d74e35b)
