media: ov5640: fix auto controls values when switching to manual mode
[ Upstream commit a8f438c684eaa4cbe6c98828eb996d5ec53e24fb ]
When switching from auto to manual mode, V4L2 core is calling
g_volatile_ctrl() in manual mode in order to get the manual initial value.
Remove the manual mode check/return to not break this behaviour.
