[PATCH 1/5] x86/setup: remove unreachable memblock_reserve() return value check

[Sang-Heon Jeon]

trim_snb_memory() runs from early_reserve_memory() in setup_arch(), before
e820__memblock_setup() calls memblock_allow_resize(). At that point
memblock_reserve() either succeeds or panics, never returning an error.

Therefore the return value check is unreachable, so remove it and the
related logic.

No functional change.
