[PATCH -next] clk: sunxi-ng: sun9i-a80: Fix wrong pointer passed to PTR_ERR()

[Wei Yongjun]

From: Wei Yongjun <weiyongjun1 at huawei.com>

PTR_ERR should access the value just tested by IS_ERR, otherwise
the wrong error code will be returned.

Fixes: 783ab76ae553 ("clk: sunxi-ng: Add A80 Display Engine CCU")
