Mirroring doesn't work with Dynamic NH mode and header disabled

[Shashikiran H]

Version: 3.2.0.0-3~mitaka

Topo:
cfgm: nodec22, nodeg10, nodec26
control: nodec22,nodec26,nodeg10
compute: nodeg8,nodeg14,nodec15(tor) and nodec11(tor), nodec32

With Dynamic NH mode and header disabled, the nh entry for the mirror entry is this:

root@nodec32:~# mirror -b
Mirror Table

Flags:D=Dynamic Mirroring

Index NextHop Flags VNI
------------------------------------------------
    0 42 18

root@nodec32:~# nh --get 42
Id:42 Type:Tunnel Fmly: AF_INET Rid:0 Ref_cnt:5 Vrf:0
              Flags:Valid, MPLSoUDP,
              Oif:0 Len:14 Flags Valid, MPLSoUDP, Data:00 25 90 c5 61 b4 00 25 90 c3 0a ee 08 00
              Vrf:0 Sip:10.204.217.17 Dip:10.204.217.48

But mirroring does not happen. The packets do not reach the tap or node hosting the mirror vm either.

if any label Change for the bridge route happen rebake for the label is
not happening due to that always pointing to old label.
