[PATCH] statd: not unlinking host files

[Steve Dickson <SteveD@redhat.com>]

Again working with the state file code, I notice that statd was
not unlinking hosts files when the kernel sent up the 
sm_unmon messages. This following patch address the reason why... 

Comments?

    statd: not unlinking host files
    
    Statd is not unlinking host files during SM_UNMON and
    SM_UNMON_ALL calls because the given host is still on the run-time
    notify list (rtnl) and the check flag is set when xunlink() is
    called. But the next thing the caller of xunlink() does is
    remove the host from the rtnl list which means the
    unlink will never happen.
    
    So in cases where xunlink() is immediately follow by a call
    to nlist_free() (which removes the host from the list) the
    check flag to xunlink() is not set.
