sd: Switch to byte-based block access
Sector-based blk_write() should die; switch to byte-based
blk_pwrite() instead. Likewise for blk_read().
Greatly simplifies the code, now that we let the block layer
take care of alignment and read-modify-write on our behalf :)
In fact, we no longer need to include 'buf' in the migration
stream (although we do have to ensure that the stream remains
compatible).
