net: sgi: ioc3-eth: Fix return value check in ioc3eth_probe()
In the function devm_platform_ioremap_resource(), if get resource
failed, the return value is ERR_PTR() not NULL. Thus it must be
replaced by IS_ERR(), or else it may result in crashes if a critical
error path is encountered.
Fixes: 0ce5ebd24d25 ("mfd: ioc3: Add driver for SGI IOC3 chip")
