Subject: RDMA/hns: Remove unnecessary platform_get_resource() error check
Patch-mainline: v4.16-rc1
Git-commit: 0b5fe5c43ab67130d259d800fcc109c7340acb63
References: bsc#1104427 FATE#326416

devm_ioremap_resource() already checks if the resource is NULL, so
remove the unnecessary platform_get_resource() error check.
