Fix unlikely double free in PKINIT client code

In pa_pkinit_gen_req, if the cleanup handler is reached with non-zero
retval and non-null out_data, out_data is freed, then dereferenced,
then freed again. This can only happen if one of the small fixed-size
malloc requests fails after pkinit_as_req_create succeeds, so it is
unlikely to occur in practice.
