gpu: nvgpu: Remove simulation WAR

The WAR put into simulation to avoid a simulator crash can now be
removed (c85be1a0968de813fe9b99ebd5c261dcb0ca8875). The first issue
with the failing test was found to be GPFIFO entries that were not
invalid.

Other issues are still present with the test and are fixed in a
later commit.
