[PATCH -next] mmc: aspeed: Fix return value check in aspeed_sdc_probe()

[Wei Yongjun <weiyongjun1@xxxxxxxxxx>]

In case of error, the function of_platform_device_create() returns
NULL pointer not ERR_PTR(). The IS_ERR() test in the return value
check should be replaced with NULL test.

Fixes: 09eed7fffd33 ("mmc: Add support for the ASPEED SD controller")
