fastboot: sparse: resync common/image-sparse.c (part 1)

Browse source 
This file originally came from upstream code.

While retaining the storage abstraction feature, this is the first
set of the changes required to resync with the
  cmd_flash_mmc_sparse_img()
in the file
  aboot.c
from
  https://us.codeaurora.org/cgit/quic/la/kernel/lk/plain/app/aboot/aboot.c?h=LE.BR.1.2.1
