fix #H248 - 'speed monster' zap message not always necessary

Browse Source 
From a bug report:  zapping wand
of speed monster (or slow monster) at an immobile monster would give the
usual '<mon> is moving faster" (or slower) message even though the monster
couldn't move at all.  This fixes that for monsters who can never move
and also for monsters who are temporarily paralyzed or asleep, although I
wonder whether speed change magic ought to also snap the latter out of it.
