Bluetooth: RFCOMM - Fix info leak via getsockname()
[ Upstream commit 9344a972961d1a6d2c04d9008b13617bcb6ec2ef ]
The RFCOMM code fails to initialize the trailing padding byte of struct
sockaddr_rc added for alignment. It that for leaks one byte kernel stack
via the getsockname() syscall. Add an explicit memset(0) before filling
the structure to avoid the info leak.
