Reset r_shadow_occlusion_buf on vid_restart. Fixes query buffer dangling pointer

Basically, when coronas appear when r_coronas_occlusionquery is 1, the engine
binds to a query buffer and stores a pointer to it in r_shadow_occlusion_buf.
Upon vid_restart, somewhere along the way, the buffer is cleared but the
original pointer is kept, resulting in a crash next time a corona appears.
