media: lgdt3306a: Fix a double kfree on i2c device remove

[ Upstream commit 94448e21cf08b10f7dc7acdaca387594370396b0 ]

Both lgdt33606a_release and lgdt3306a_remove kfree state, but _release is
called first, then _remove operates on states members before kfree'ing it.
This can lead to random oops/GPF/etc on USB disconnect.
