No more rescheduling for pending messages after DownloadMmsAction is
failed caused by outside window. Any pending download messages will be
remained as the DOWNLOADING state without actual downloading operations
and sending a DEFERRED M-NotifyResp.ind even.
It will reschedule pending messages whenever sending or downloading is
failed including outside window failure case. And it also removes dup
scheduling and fix some typo.
