    bluetooth socket sysinit: correct memset initialization

    gcc -Wmemset-elt-size diagnosed this.  The code was only initializing
    the first 1/sizeof(long) bytes.  On 64-bit systems, this would mean only
    events up to 0x20 were initialized.

    This effectively reverses the security policy for some events with
    higher ids, now permitting them on unprivileged sockets.  Two that are
    defined are NG_HCI_EVENT_LE (0x3e) and NG_HCI_EVENT_BT_LOGO (0xfe).
