media: vimc: handle error in vimc_add_subdevs
In case the 'add' callback of an entity fails,
then all other entities should unregister and released.
This should be done inside vimc_add_subdevs so that
the function handles its own failure.
In order to call vimc_unregister_subdevs and vimc_release_subdevs from
vimc_add_subdevs, the order of the function should change.
