  Fix #2117: crash if either combatant was guaranteed to die

Regression from commit f6c4f3d214f5619ece6b934d0d1003ca2f1020e7.

The code divided by zero and the probability to stay unscathed ended up as
NaN, which triggered an assertion failure if the AI simulated one more
fight for either combatant.
