[10214] Small final (as i think ;) ) fixes for restricted flight zone

* Fixed my horriable typo in 58600 effect code. Thanks to zergtmn for pointing to it.
* Remove redundent cast 45472 in 58600 effect code (it casted from 58601 already). Thanks to porteyoplait.
* Prevent restart 58600 debuf timer at temporary leave zone and return to it.
