Commit 42011be1e disabled HiZ when sharing depth buffer externally,
which free HiZ buffer.
But in emit_depth_packets() we use that buffer, which generates a crash
in
"piglit.spec.egl_khr_gl_image.egl_khr_gl_renderbuffer_image-clear-shared-image
gl_depth_component24" test when running in Skylake.
This commit avoids using HiZ when the buffer was free.
v2: detect earlier we don't have HiZ buffer (Jason)
