media: hi846: Fix memleak in hi846_init_controls()

Browse Source 
hi846_init_controls doesn't clean the allocated ctrl_hdlr
in case there is a failure, which causes memleak. Add
v4l2_ctrl_handler_free to free the resource properly.

Fixes: e8c0882685 ("media: i2c: add driver for the SK Hynix Hi-846 8M pixel camera")
