Update Documentation/usb/proc_usb_info.txt:

- add a blank line before each T: line to match current kernel
  and to make the text more readable.

The percentage is how much of the "reserved" bandwidth is scheduled by

For example, default settings may not use more than a small
amount of periodic bandwidth. To use significant fractions
of bus bandwidth, drivers must select a non-default altsetting.
Only one setting for an interface may be active at a time, and
only one driver may bind to an interface at a time. Most devices
have only one alternate setting per interface.
