mm/memblock.c: trivial code refine in memblock_is_region_memory()

memblock_is_region_memory() invoke memblock_search() to see whether the
base address is in the memory region.  If it fails, idx would be -1.
Then, it returns 0.

If the memblock_search() returns a valid index, it means the base
address is guaranteed to be in the range memblock.memory.regions[idx].
Because of this, it is not necessary to check the base again.

This patch removes the check on "base".
