[PATCH] drm/amdgpu: fix structurally dead code vcn_v2_5_hw_init

["Gustavo A. R. Silva" <gustavo@embeddedor.com>]

Notice that there is a *continue* statement in the middle of the
for loop and that prevents the code below from ever being reached:

	r = amdgpu_ring_test_ring(ring);
	if (r) {
		ring->sched.ready = false;
		goto done;
	}

Fix this by removing the continue statement and updating ring->sched.ready
to true before calling amdgpu_ring_test_ring(ring).

Notice that this fix is based on
commit 1b61de45dfaf ("drm/amdgpu: add initial VCN2.0 support (v2)")

Addresses-Coverity-ID 1485608 ("Structurally dead code")
Fixes: 28c17d72072b ("drm/amdgpu: add VCN2.5 basic supports")
