Subject: [PATCH] Fix uncommon PKINIT memory leak
PKINIT per-request module data objects are normally created by
pkinit_server_verify_padata() and freed by
pkinit_server_return_padata(). In some unusual circumstances, the KDC
may not call the return_padata method after verification succeeds.
Add a free_modreq method and free the object there instead.
