[PATCH] PM: AVS: rockchip-io: Fix error return code in rockchip_iodomain_probe()

[Zhang Changzhong]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: e943c43b32ce ("PM: AVS: rockchip-io: Move the driver to the rockchip 
specific drivers")
