nvme: fixup scan failure for non-ANA multipath controllers
Commit 62baf70c3274 caused the ANA log page to be re-read, even on
controllers that do not support ANA. While this should generally
harmless, some controllers hang on the unsupported log page and
never finish probing.
Fixes: 62baf70c3274 ("nvme: re-read ANA log page after ns scan completes")
