Some servers (e.g. Azure) return "STATUS_NOT_IMPLEMENTED" rather
than "STATUS_INVALID_DEVICE_REQUEST" on query network interface
info at mount.  This shouldn't cause us to log a warning message
automatically but does because we were not checking for ENOSYS.
According to checkpatch we shouldn't be using ENOSYS for this
in any case so fix it by mappoing to EOPNOTSUPP so we
don't log this unless noisier cifsFYI is enabled.

Subject: [PATCH] smb3: do not display confusing message on mount to Azure
 servers

Some servers (e.g. Azure) return "STATUS_NOT_IMPLEMENTED" rather
than "STATUS_INVALID_DEVICE_REQUEST" on query network interface
info at mount.  This shouldn't cause us to log a warning message
automatically.  Don't log this unless noisier cifsFYI is enabled.
