msm: camera: Add recording state machine in vfe 3.2.

-The recording state machine which was present for
earlier targets is missing in vfe 3.2. Add this to
avoid any issues that might be seen during
starting/stopping of video recording.
-Also remove the msleep during streamoff. This is
no longer needed, since the state machine handles
this case properly.
