drm/amdgpu: partially revert "reduce reset time"

Browse Source 
This partially reverts commit 194eb174cb.

This commit introduced a new state variable into adev without even
remotely worrying about CPU barriers.

Since we already have the amdgpu_in_reset() function exactly for this
use case partially revert that.
