net/mlx5e: Fix SWP offsets when vlan inserted by driver

net/mlx5e: Fix SWP offsets when vlan inserted by driver

BugLink: https://bugs.launchpad.net/bugs/1914447
In case WQE includes inline header the vlan is inserted by driver even
if vlan offload is set. On geneve over vlan interface where software
parser is used the SWP offsets should be updated according to the added
vlan.
