Daniel Bristot de Oliveira df2d221e93 rtla/hwnoise: Reduce runtime to 75%
[ Upstream commit 7bc4d3089a ]

osnoise runs 100% of time by default. It makes sense because osnoise
is preemptive. hwnoise checks preemption once a second, so it
reduces system progress.

Reduce runtime to 75% to avoid problems by default. I added a Fixes
as it might avoid problems for first time users as it lands on distros.
