drm/i915: Add a spinlock to protect the active_list
This is a baby-step in the direction of having finer-grained locking than the struct_mutex. Specifically, this will enable new debugging code to read the active list for printing out GPU state when the GPU is wedged, (while the struct_mutex is held, of course).
