[PATCH v2 RESEND 2/2] nvme: Update nvme_scan_namespace to keep trying on busy

[Moritz Fischer <moritzf@google.com>]

A busy controller shouldn't be game-over for all controllers,
so keep trying on hitting -EBUSY.

This change brings the actual behavior of the routine in line
with what the descriptions says.
