fix recent Wounded_legs fix

Wounded_legs was changed from (HWounded_legs || EWounded_legs) to
just (HWounded_legs), but when the timeout code decremented the timer
to 0, HWounded_legs became 0 and heal_legs() operated as if there was
nothing to repair and hero didn't recover from temporarily lost Dex.
Change Wounded_legs back to (HWounded_legs || EWounded_legs).
