MLK-16536-15 video: fbdev: dcss: improve cfifo wrapping handling

After changing the strategy to 'flush cfifo once per frame',
the cfifo wrapping handling should also be changed accordingly.
Now, when it is found that the cfifo has no enough room from 'in'
to the buffer end to hold the current commit, the 'commit_cfifo'
will cancel this commit and flush the cfifo workqueue before
restart the commit again.
