doc: fix RSA_set_method return value documentation

The documentation incorrectly stated that RSA_set_method() returns
a pointer to the old RSA_METHOD. In fact, it returns int (1 for success).
The SYNOPSIS correctly shows 'int RSA_set_method(...)' but the
RETURN VALUES section was wrong.

Fixes #13884

CLA: trivial
