drm/vc4: Fix memory leak of BO array in hang state

[ Upstream commit f4dfd6847b3e5d24e336bca6057485116d17aea4 ]

The hang state's BO array is allocated separately with kzalloc() in
vc4_save_hang_state() but never freed in vc4_free_hang_state(). Add the
missing kfree() for the BO array before freeing the hang state struct.

Fixes: 214613656b51 ("drm/vc4: Add an interface for capturing the GPU state after a hang.")
