gpu: nvgpu: tu104: remove smpc extended buffer workaround

Browse Source 
In Turing, SMPC gets fe2all_freeze, so extended buffer workaround
is not needed. This workaround has been removed from Ucode, but
not from kernel, this causes smpc counters to either not start or
not stop in some cases.

Bug 2420353
