Subject: drm/i915/selftests: Drop vestigal timeslicing assert
Git-commit: cf4c826d96da8784a711c4bf84d656a93c1280bf
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Since the semaphore interrupt may cause us to yield the timeslice
immediately, we may cancel the timer before we notice the submission is
complete. The assertion is no longer valid due to the race with the
interrupt.
