[PATCH v1 2/2] nvme: remove warning for shared ns when multipath=N

[Daniel Wagner]

The default value for the module parameter multipath is Y, thus the user
has actively chosen to set multipath to N to trigger this warning with
shared namespaces.

There is at least one external mutlipathing module which conflict with
the native multipathing feature (Dell's PowerPath module). In such setups
the native mutlipathing is deliberate disabled but the warning
that mutlipathing is not supported is confusing users.

The warning was added in ce8d78616a6b ("nvme: warn about shared
namespaces without CONFIG_NVME_MULTIPATH"). In the mean time the config
option has been dropped. Because multipath is now always built-in and
the default is Y, just drop the warning.
