media: s5p-mfc: fix a couple double frees in probe
Commit Message
The extra calls to video_device_release() are a bug, we free these after
the goto.
Fixes: c974c436eaf4 ('s5p-mfc: Fix race between s5p_mfc_probe() and s5p_mfc_open()')

This code would be easier to understand if it didn't use "come from"
style label names so that "goto release_dec;" would release dec etc
instead of "goto register_dec;"
