Volker Ruppert 5bc1717adc Removed the data tranfer limit for read/write commands.
- The read buffer is now limited to 16 sectors and the read commands can fill
  it multiple times until all sectors have been read.
- The write commands are currently not using the device buffer, so no panic
  should happen here.
