Do not stop kernel shrinker on lock contention
Lock contention, by itself, shouldn't indicate a stop condition to the
kernel's slab shrinker. Doing so can cause stalls when the kernel is
trying to free large parts of the cache such as is done by drop_caches
Also, perhaps arc_reclaim_lock should be a spinlock, and this code
eliminated.
