vlan: Fix build error wth vlan_get_encap_level()

Browse Source 
The new function vlan_get_encap_level() uses vlan_dev_priv()
which is only conditionally avaialble when VLAN support is
enabled.  Make vlan_get_encap_level() conditionally available
as well.

Fixes: 44a4085538 ("bonding: Fix stacked device detection in arp monitoring")
