Mathias Krause 9344a97296 Bluetooth: RFCOMM - Fix info leak via getsockname() 
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.
