[SRU][B/C/D][CVE-2019-11884] Add null byte to avoid overflow

>From the link above:

    "The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the 
    Linux kernel before 5.0.15 allows a local user to obtain potentially 
    sensitive information from kernel stack memory via a HIDPCONNADD command, 
    because a name field may not end with a '\0' character."

Clean cherry pick for all releases.

This patch made its way into Xenial by way of an upstream stable sync
(LP: #1830176).

It is already in unstable.
