nvgpu: Remove ASYNC PROBE for vgpu

Browse Source 
Async probe of vgpu driver results in a race condition where GICD registers
are being programmed incorrectly because of the race.

Remove ASYNC_PROBE for vgpu driver as a WAR to prevent it. This change
would be reverted after GICD register programming is serialized
