drm/radeon: fix UVD suspend error
I met a bug recently and the kernel log:
[ 330.171875] radeon 0000:03:00.0: couldn't schedule ib
[ 330.175781] [drm:radeon_uvd_suspend [radeon]] *ERROR* Error destroying UVD (-22)!
In radeon drivers, using UVD suspend is as follows:
if (rdev->has_uvd) {
uvd_v1_0_fini(rdev);
radeon_uvd_suspend(rdev);
}
In radeon_ib_schedule function, we check the 'ring->ready' state,
but in uvd_v1_0_fini funciton, we've cleared the ready state.
So, just modify the suspend code flow to fix error.
