qlcnic: info leak in qlcnic_dcb_peer_app_info()
This function is called from dcbnl_build_peer_app(). The "info"
struct isn't initialized at all so we disclose 2 bytes of uninitialized
stack data. We should clear it before passing it to the user.
Fixes: 48365e485275 ('qlcnic: dcb: Add support for CEE Netlink interface.')
