hfsplus: ensure bio requests are not smaller than the hardware sectors
commit 6596528e391ad978a6a120142cba97a1d7324cb6 upstream.
Currently all bio requests are 512 bytes, which may fail for media
whose physical sector size is larger than this. Ensure these
requests are not smaller than the block device logical block size.
