fix the double free error

in SDL_uikitview the variable 'textfield' is initialialized and set to autorelease.
however in the dealloc method a second [release] is sent.
If the textfield has not been set to nil before (with a viewDidUnload for example) this can lead to awful hard-to-find crashes when the SDL code terminates.

the error message is
-[textfield release] message sent to deallocated instance 0x4e5fa90

the fix is simple, just release the object as soon as it is added to the subview, see attached patch
