media: rockchip/rga: fix error handling in probe
There are a few bugs in this code. 1) No checks for whether
dma_alloc_attrs() or __get_free_pages() failed. 2) If
video_register_device() fails it doesn't clean up the dma attrs or the
free pages. 3) The video_device_release() function frees "vfd" which
leads to a use after free on the next line. The call to
video_unregister_device() is not required so I have just removed that.
