HID: fix kerneldoc comment for hid_input_report()

The kerneldoc comment for 'interrupt' has already confused a lot
of people, as it is simply wrong. It doesn't carry the information
about the context, but is used to distinguish between two fundamental
types of low-level transport transfers -- interrupt vs. control.

Make this clear in the comment.
