disk: part: align buffer so it can be used with DMA enabled drivers

When using ISO partitions with a DMA enabled block device driver
reading the ISO partition leads to unaligned DMA operations:
  CACHE: Misaligned operation at range [bffb7da8, bffb85a8]

Align the buffer to make sure we pass a buffer which works for
DMA operations.
