    sock_diag: Fix out-of-bounds access to sock_diag_handlers[]
    
    [ Upstream commit 6e601a53566d84e1ffd25e7b6fe0b6894ffd79c0 ]
    
    Userland can send a netlink message requesting SOCK_DIAG_BY_FAMILY
    with a family greater or equal then AF_MAX -- the array size of
    sock_diag_handlers[]. The current code does not test for this
    condition therefore is vulnerable to an out-of-bound access opening
    doors for a privilege escalation.
