ALSA: line6: Improve line6_read/write_data() interfaces
The address cannot be negative so make it unsigned. Also, an unsigned
int is always sufficient for the length, so no need to overdo it with a
size_t. Finally, add in range checks to see if the values passed in
actually fit where they are used.
