commit 0268a7cc7fdc47d90b6c18859de7718d5059f6f1 upstream.
4byte padding cause the connection issue with the applications of MacOS. smb2_close response size increases by 4 bytes by padding, And the smb client of MacOS check it and stop the connection. This patch use struct_group_attr instead of struct_group for network_open_info to use __packed to avoid padding.
