s390/zcrypt: fix memory leak with ap configuration data
The ap_query_configuration function allocates the ap_config_info structure, but there is no code to free the structure. Allocate the structure in the module_init function and free it again in module_exit. While we are at it simplify a few functions in regard to the ap configuration data.
