floppy: call disk_force_media_change when changing the format

While changing the format of a floppy isn't strictly speaking a media
change, the effects are the same in that the content of the media
changes and the diskseq should be increased and uevent should be
sent.  Switch from calling __invalidate_device to
disk_force_media_change to do so.
