    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 this patch removes the check flag from xunlink() since
    its not needed and correctly allocates and frees memory
    used by xunlink().
