Tzafrir Cohen ffdfdfb66b xpp_usb: Fix potential corruption on clock rewind 
The xpp modules use time differences for various statistics. In one case
xpp_usb creates a histogram of the time it took the system to send USB
packets (URBs). The time difference is used (after adjustments) as an
index to that array.

However if the clock happens to go back at that exact point in time, we
get to write to an arbitrary negative index in this array.
