On passing NULL as a last parameter to xxx_create_ext_with_params(),
rxa_config_params_validate() uses default values and dereferences
NULL pointer leading to segmentation fault.
Fixed by returning after using default values without dereferencing
NULL pointer.
Fixes: 8be6c94d6d90 ("eventdev/eth_rx: add new adapter create API")
