[PATCH] mv643xx_eth: fix return value check in mv64x60_eth_register_shared_pdev()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

In case of error, the function platform_device_register_simple() returns
RR_PTR() and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().
