[PATCH net-next 2/3] net: sparx5: fix return value check in sparx5_create_targets()

[Yang Yingliang <yangyingliang@huawei.com>]

In case of error, the function devm_ioremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should
be replaced with NULL test.

Fixes: 3cfa11bac9bb ("net: sparx5: add the basic sparx5 driver")
