nvme: fixup scan failure for non-ANA multipath controllers

Browse Source 
commit 26d7fb4fd4 upstream.

Commit 62baf70c32 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: 62baf70c32 ("nvme: re-read ANA log page after ns scan completes")
