If query interface info returns error not supported (as it does to Samba eg.)
don't log a noisy warning on every mount - change to an FYI level so doesn't
clutter the logs.

Subject: [PATCH] smb3: remove noisy warning message on mount

Some servers, like Samba, don't support the fsctl for
query_network_interface_info so don't log a noisy warning
message on mount for this by default unless the error is more serious.
Lower the error to an FYI level so it does not get logged by
default.
