[PATCH v2] mm: memory-failure: directly use IS_ENABLED(CONFIG_HWPOISON_INJECT)

[Kefeng Wang <wangkefeng.wang@huawei.com>]

It's more clear and simple to just use IS_ENABLED(CONFIG_HWPOISON_INJECT)
to check whether or not to enable HWPoison injector module instead of
CONFIG_HWPOISON_INJECT/CONFIG_HWPOISON_INJECT_MODULE.
