vmxnet3: disable overlay offloads if UPT device does not support
'Commit 6f91f4ba046e ("vmxnet3: add support for capability registers")'
added support for capability registers. These registers are used
to advertize capabilities of the device.
The patch updated the dev_caps to disable outer checksum offload if
PTCR register does not support it. However, it missed to update
other overlay offloads. This patch fixes this issue.
