    tools/net/ynl: fix cli.py --subscribe feature

    Execution of command:
    ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml /
            --subscribe "monitor" --sleep 10
    fails with:
      File "/repo/./tools/net/ynl/cli.py", line 109, in main
        ynl.check_ntf()
      File "/repo/tools/net/ynl/lib/ynl.py", line 924, in check_ntf
        op = self.rsp_by_value[nl_msg.cmd()]
    KeyError: 19

    Parsing Generic Netlink notification messages performs lookup for op in
    the message. The message was not yet decoded, and is not yet considered
    GenlMsg, thus msg.cmd() returns Generic Netlink family id (19) instead of
    proper notification command id (i.e.: DPLL_CMD_PIN_CHANGE_NTF=13).

    Allow the op to be obtained within NetlinkProtocol.decode(..) itself if the
    op was not passed to the decode function, thus allow parsing of Generic
    Netlink notifications without causing the failure.
