drm/amdgpu: Fix NULL dereference in amdgpu_ualink_info_set_accel_state

Browse source

Commit 0a6da5dcfe ("drm/amdgpu: Improve ualink state transitions")
introduced an access to info->accel_state before checking whether info
is NULL.

Move the access after the NULL check to avoid a potential NULL pointer
dereference.
