Subject: cciss: fix info leak in cciss_ioctl32_passthru()

commit 58f09e00ae095e46ef9edfcf3a5fd9ccdfad065e upstream.

The arg64 struct has a hole after ->buf_size which isn't cleared.  Or if
any of the calls to copy_from_user() fail then that would cause an
information leak as well.

This was assigned CVE-2013-2147.
