[PATCH v3 1/8] media: i2c: ov9282: handle error from exposure range update

[Richard Leitner <richard.leitner@linux.dev>]

When setting V4L2_CID_VBLANK the V4L2 range for the exposure control is
updated by v4l2_ctrl_modify_range(). This range update missed a return
value check, which resulted in ov9282_set_ctrl() not returning on an error
from that function call.

Fix this by checking the return value and returning it on error.
