ASoC: samsung: Fix return value check in s3c2412_iis_dev_probe()

Browse source 
In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR(). Also remove redundant return value check of
platform_get_resource().
