st-hva: fix some error handling in hva_hw_probe()
commit 6b2bed891253c08e7f4c17dbd46b71fc87f22eef upstream. The devm_ioremap_resource() returns error pointers, never NULL. The platform_get_resource() returns NULL on error, never error pointers. The error code needs to be set, as well. The current code returns PTR_ERR(NULL) which is success.
