    When a policy expiration is triggered from user space the request
    travels through km_policy_expired and ultimately into
    xfrm_exp_policy_notify which calls build_polexpire.  build_polexpire
    uses the netlink port passed to km_policy_expired as the source port for
    the netlink message it builds.
    
    When a state expiration is triggered from user space the request travles
    through km_state_expired and ultimately into xfrm_exp_state_notify which
    calls build_expire.  build_expire uses the netlink port passed to
    km_state_expired as the source port for the netlink message it builds.
    
    Pass nlh->nlmsg_pid from the user generated netlink message that
    requested the expiration to km_policy_expired and km_state_expired
    instead of current->pid which is not a netlink port number.
