Nicola Tuveri 0c5d725ebf Fix segfault in RSA_free() (and DSA/DH/EC_KEY) ... `RSA_free()` and friends are called in case of error from `RSA_new_method(ENGINE *e)` (or the respective equivalent functions). For the rest of the description I'll talk about `RSA_*`, but the same applies for the equivalent `DSA_free()`, `DH_free()`, `EC_KEY_free()`. If `RSA_new_method()` fails because the engine does not implement the required method, when `RSA_free(RSA *r)` is called, `r->meth == NULL` and a segfault happens while checking if `r->meth->finish` is defined. This commit fixes this issue by ensuring that `r->meth` is not NULL before dereferencing it to check for `r->meth->finish`. Fixes #7102 .
