net/vlan: Provide read access to the vlan egress map
Provide a method for read-only access to the vlan device egress mapping. Do this by refactoring vlan_dev_get_egress_qos_mask() such that now it receives as an argument the skb priority instead of pointer to the skb. Such an access is needed for the IBoE stack where the control plane goes through the network stack. This is an add-on step on top of commit d4a968658c "net/route: export symbol ip_tos2prio" which allowed the RDMA-CM to use ip_tos2prio.
