Crash while perfoming connect by setting connect atempt count below the NUM_MTU_SIZES

[kaede1003]

i found a crash while i am perfoming connect from rakpeer::connect interface by passing the connect atempt count below NUM_MTU_SIZES( <3 )

See rakpeer.cpp at line 5919
int MTUSizeIndex = rcs->requestsMade / (rcs->sendConnectionAttemptCount/NUM_MTU_SIZES);
if value of rcs->sendConnectionAttemptCount is below NUM_MTU_SIZES, the divied by zero issue will be occured.

should be easy to fix it up
