media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries

In the Linux kernel, the following vulnerability has been resolved:

media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries

The allocation failure of mycs->yuv_scaler_binary in load_video_binaries()
is followed with a dereference of mycs->yuv_scaler_binary after the
following call chain:

sh_css_pipe_load_binaries()
  |-> load_video_binaries(mycs->yuv_scaler_binary == NULL)
  |
  |-> sh_css_pipe_unload_binaries()
        |-> unload_video_binaries()

In unload_video_binaries(), it calls to ia_css_binary_unload with argument
&pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the
same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer
dereference is triggered.
