vlan: Set correct source MAC address with TX VLAN offload enabled

vlan: Set correct source MAC address with TX VLAN offload enabled

With TX VLAN offload enabled the source MAC address for frames sent using the
VLAN interface is currently set to the address of the real interface. This is
wrong since the VLAN interface may be configured with a different address.

The bug was introduced in commit 25972fef22fff2e81a79a7dbf123a7e2981192ad
("vlan: Fix header ops passthru when doing TX VLAN offload.").

This patch sets the source address before calling the create function of the
real interface.
