crypto/evp/ctrl_params_translate.c: fix a typo in the error message

The ERR_raise_data() call on failure to find ctx->p2 in str_value_map
erroneously refers to ctx->p1 instead;  fix that but supplying the
correct field and casting it to the supposed const char * type.

Fixes: 9a1c4e41e8d3 "EVP: Implement data-driven translation between known ctrl and OSSL_PARAMs"
