Bluetooth: HCI - Fix info leak via getsockname()
[ Upstream commit 3f68ba07b1da811bf383b4b701b129bfcb2e4988 ]
The HCI code fails to initialize the hci_channel member of struct
sockaddr_hci and that for leaks two bytes kernel stack via the
getsockname() syscall. Initialize hci_channel with 0 to avoid the
info leak.
