drivers/block/floppy.c: remove unnecessary argument from [__]reschedule_timeout

Prior to patch "drivers/block/floppy.c: Use pr_<level>" only
reschedule_timeout(,"request done"...) printed a numeric value after a
reschedule_timeout event message.

Restore that behavior and remove the now unnecessary argument.
