staging: mt7621-eth: fix return value check in mtk_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: e3cbf478f846 ("staging: mt7621-eth: add the drivers core files")
