[RFC 3/3] Revert "rcutorture: Tweak kvm options"

From: Joel Fernandes (Google)
Date: Mon Jul 01 2019 - 00:05:03 EST


This reverts commit a6fda6dab93c2c06ef4b8cb4b9258df6674d2438 which
causes kvm.sh to not run on my machines. The qemu-system-x86_64 command
runs but does nothing.

I am Ok if we want to drop this patch but it is in my tree because
without it I can't run the tests.
