ksmbd: set FILE_NAMED_STREAMS attribute in FS_ATTRIBUTE_INFORMATION

commit 728f14c72b71a19623df329c1c7c9d1452e56f1e upstream.

If vfs objects = streams_xattr in ksmbd.conf FILE_NAMED_STREAMS should
be set to Attributes in FS_ATTRIBUTE_INFORMATION. MacOS client show
"Format: SMB (Unknown)" on faked NTFS and no streams support.
