    linux: require vnet(9) context in ifname_bsd_to_linux_name()
    
    This function is used by netlink(9) only.  The netlink(9) taskqueue thread
    runs in the vnet of the socket whose request the thread is processing
    right now.  This is a correct vnet and resetting it to vnet0 is incorrect.
    If the function is to be used by any other caller in addition to
    netlink(9), it would be caller's responsiblity to provide correct vnet(9).
