remove sanity check from ossl_rsa_todata

Theres no reason we should gate ossl_rsa_todata on there being a minimum
set of parameters. EVP_PKEY_todata makes no guarantees about the
validity of a key, it only returns the parameters that are set in the
requested key, whatever they may be.  Remove the check.

Fixes #21935
