Comment out unused parameters instead of (void) cast. (firebird-sdbc)

Firebird doesn't support catalogs or schemas hence these parameters
are unused in the various get[...] methods. Previously these were (void)
casted however commenting out the parameters seems more correct and reduces
the amount of code.

(This was omitted for as-of-yet unimplemented methods since they will still
 be looked at in detail.)
