media: v4l2: move v4l2_ext_controls conversion
The v4l2_ext_controls ioctl handlers use an indirect pointer to an
incompatible data structure, making the conversion particularly tricky.
Moving the compat implementation to use the new
v4l2_compat_get_user()/v4l2_compat_put_user() helpers makes it
noticeably simpler.
In v4l2_compat_get_array_args()/v4l2_compat_put_array_args(),
the 'file' argument needs to get passed to determine the
exact format, which is a bit unfortunate, as no other conversion
needs these.
