ksmbd: common: use struct_group_attr instead of struct_group for network_open_info

commit 0268a7c 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.
