ANDROID: memblock: do not track obsolete_checksetup and do_early_param

Originally I've added memsize logic to track memblock memory allocated
at the obsolete_checksetup and do_early_param. That showed size with its
param name.

But nowadays we don't see that big memory allocation in that early
param. To simplify memsize code, let me remove related code. Some code
like memblock_memsize_free will be remained for the next commits.
