[PATCH 2/5] sh: remove unreachable memblock_reserve() return value check

[Sang-Heon Jeon <ekffu200098@gmail.com>]

reserve_crashkernel() runs from early_reserve_mem() in paging_init(),
before the same function 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.
