[ Upstream commit fbd6a42d8932e172921c7de10468a2e12c34846b ]

When nvme_round_robin_path() finds a valid namespace we should be
using it;
falling back to __nvme_find_path() for non-optimized paths will cause
the
result from nvme_round_robin_path() to be ignored for non-optimized
paths.

Hello Sasha,

this patch needs a fix that I recently submitted to linux-nvme.
The same holds for the respective 5.7 and 5.4 AUTOSEL patches.

I'll grab it too, thanks!
