[PATCH 29/34] net/shaper: replace sleep_on() with wait_event()

[Nishanth Aravamudan <nacc@xxxxxxxxxx>]

Hi,

Please consider applying.

Description: Use wait_event() instead of the deprecated sleep_on().
Move the in_interrupt() check outside loop, as I do not believe the
process context should change once execution has begun. Patch is
compile-tested.
