Boris Brezillon 9ad970c8a1 drm/vc4: Fix NULL pointer dereference in vc4_save_hang_state() ...

commit 17b11b76b8 upstream.

When saving BOs in the hang state we skip one entry of the
kernel_state->bo[] array, thus leaving it to NULL. This leads to a NULL
pointer dereference when, later in this function, we iterate over all
BOs to check their ->madv state.

Fixes: ca26d28bba ("drm/vc4: improve throughput by pipelining binning and rendering jobs")
