[PATCH] ARM: imx: introduce function imx_free_mx3_camera

We forgot to free pdev->dev.dma_mask on error after
having called the imx_alloc_mx3_camera function.
This patch introduces the imx_free_mx3_camera function
that adds the missing kfree call and is practical for
future usage with imx_alloc_mx3_camera().
