staging: mt7621-eth: fix return value check in mt7621_gsw_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: f079b6406348 ("staging: mt7621-eth: add gigabit switch driver (GSW)")
