Adam D. Moss 666aa69f32 Non-l2arc pool reads shouldn't be l2arc misses ... The current l2_misses accounting behavior treats all reads to pools without a configured l2arc as an l2arc miss, IFF there is at least one other pool on the system which does have an l2arc configured. This makes it extremely hard to tune for an improved l2arc hit/miss ratio because this ratio will be modulated by reads from pools which do not (and should not) have l2arc devices; its upper limit will depend on the ratio of reads from l2arc'd pools and non-l2arc'd pools. This PR prevents ARC reads affecting l2arc stats (n.b. l2_misses is the only relevant one) where the target spa doesn't have an l2arc.
