[PATCH 4/8] drm/amdgpu: coding style of amdgpu_vm_is_gpu_reset

[deathsimple@xxxxxxxxxxx (Christian König)]

From: Christian König <christian.koenig@xxxxxxx>

The name is a bit confusing and the extra "? true : false" is superflous.

Additional to that remove setting the reset counter directly after checking it.
