Undead: check the return value of sscanf() in execute_move()

sscanf() assigns its output in order, so if a conversion specifier fails
to match, a later "%n" specifier will also not get its result assigned.
In Undead's execute_move(), this led to the result of "%n" being used
without being initialised.  That could cause it to try to parse
arbitrary memory as part of the move string, which shouldn't be a
security problem (since execute_move() handles untrusted input anyway),
but could lead to a crash and certainly wasn't helpful.
