_XiGetExtensionVersion was called from XGetExtensionVersion and from _XiCheckExtInit. When called from _XiCheckExtInit, nothing accounted for the fact that it can return ((XExtensionVersion *) NoSuchExtension) in case of error. Also it recursively calls _XiCheckExtInit potentionally causing multiple unlocks if _XiCheckExtInit fails. -> Remove it and call directly _XiGetExtensionVersionRequest and only call _XiCheckExtInit only from XGetExtensionVersion.
