cifs: do not query ifaces on smb1 mounts

Browse Source 
Users have reported the following error on every 600 seconds
(SMB_INTERFACE_POLL_INTERVAL) when mounting SMB1 shares:

	CIFS: VFS: \\srv\share error -5 on ioctl to get interface list

It's supported only by SMB2+, so do not query network interfaces on
SMB1 mounts.

Fixes: 6e1c1c08cd ("cifs: periodically query network interfaces from server")
