x86: memblock: set current limit to max low memory address

The memblock current limit value is used to limit early boot memory
allocations below max low memory address by default, as the kernel can
access only to the low memory.

Hence, set memblock current limit value to the max mapped low memory
address instead of max mapped memory address.
