    server: set correct gateway when update vm nic on shared networks (#5105)
    
    This PR fixes the issue that nic has wrong gateway after updating vm nic.
    
    Steps to reproduce the issue
    (1) create shared network (in advanced zone or advanced zone with sg)
    (2) create new shared network (with same startip/endip/netmask, but 
different gateway).
    (3) create a vm in new network
    (4) stop vm and update vm nic ip address
    
    Expected result:
    The vm has correct gateway and netmask (of second network)
    
    Actual result:
    The vm has wrong gateway and netmask (of first network)
