cam iosched: Call cam_iosched_limiter_init() after ios->current is set to the default

The attached patch lets cam_iosched_iop_stats_init() call cam_iosched_limiter_init()
after ios->current is set to the default.

Previously ios->current was set to 0 until the first
cam_iosched_cl_maybe_steer() call.
