[PATCH v9 7/9] media: mediatek: vcodec: Fix media device node number

change media register device node number to a correct value.
The vfd minor is used to record the number of registered
video device nodes. The mdev_dec.devnode minor counter is
used to record the number of registered media device nodes.

Fixes: 41f03c673cb7b ("media: mediatek: vcodec: replace pr_* with dev_* for v4l2 debug message")
