The FAT filesystem code knows which partition ID it is operating on.
Currently, this is passed to fat_register_device() as a parameter.
In order to convert FAT to the more standardized fat_set_blk_dev(), the
information needs to come from somewhere else, and the partition
definition structure is the logical place.

v3: Set info->part in get_device_and_partition() when returning "whole
    disk" partition.
v2: No change.
