net: dsa: gswip: Fix return value check in gswip_probe()
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().
Fixes: 14fceff4771e ("net: dsa: Add Lantiq / Intel DSA driver for vrx200")
