[PATCH] rsa: fix deleting RSA keys

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

RSA keys are appended onto rsa_keys with rsa_key_add, so it makes sense
that rsa_key_free would remove them from the key ring's linked list.

It's possible to have "standalone" RSA keys outside the key ring, but
those would be global variables which can't be freed anyway.

There are no current users of this function.
