[PATCH v5 08/11] media: ov5640: Make the return rate type more explicit

[Maxime Ripard <maxime.ripard@bootlin.com>]

In the ov5640_try_frame_interval function, the ret variable actually holds
the frame rate index to use, which is represented by the enum
ov5640_frame_rate in the driver.

Make it more obvious.
