mm/memblock: drop WARN and use SMP_CACHE_BYTES as a default alignment

Don't produce warning and interpret 0 as "default align" equal to
SMP_CACHE_BYTES in case if caller of memblock_alloc_base_nid() doesn't
specify alignment for the block (align == 0).

This is done in preparation of introducing common memblock alloc interface
to make code behavior consistent.  More details are in below thread :
