cifs: reduce warning log level for server not advertising interfaces

[ Upstream commit 16a57d7681110b25708c7042688412238e6f73a9 ]

Several users have reported this log getting dumped too regularly to
kernel log. The likely root cause has been identified, and it suggests
that this situation is expected for some configurations
(for example SMB2.1).

Since the function returns appropriately even for such cases, it is
fairly harmless to make this a debug log. When needed, the verbosity
can be increased to capture this log.
