Assertion failure @ snx_sgw_driver_handle_modify_rsp

Crash was observed when we were receiving the DSReq for SGW HO, and we have already purged all the pdn before sending the DSRsp.


    1. Create a pure s call.
    2. Perform SGW S1 based HO.
    3. Delay the sx modify rsp, and then perform s11 path failure on new sgw.
    4. Before abort sess command is recieved we recieve the delayed SX Mod Rsp.
    5. Reported crash will be observed.
