[PATCH v2 4/5] media: i2c: imx415: Fix control handler initial count

[Alexander Shiyan <eagle.alexander923@gmail.com>]

Replace the initial control count of 10 with 9 + 2 to correctly
account for the two controls added by v4l2_ctrl_new_fwnode_properties()
(orientation and rotation).
The driver currently adds nine explicit controls plus up to two
fwnode-based controls, totalling 11. Using a value of 10 in
v4l2_ctrl_handler_init() may cause the control handler to run out
of preallocated storage, leading to memory corruption when the 11th
control is added.
