Currently, there is a potential problem that calling the API function
rte_eth_dev_set_vlan_offload to start VLAN hardware offloads which the
driver does not support. If the PMD driver does not support certain
VLAN
hardware offloads and does not check for it, the hardware setting will
not change, but the VLAN offloads in
dev->data->dev_conf.rxmode.offloads
will be turned on.
It is supposed to check the hardware capabilities to decide whether
the
relative callback needs to be called just like the behavior in the API
function named rte_eth_dev_configure. And it is also needed to cleanup
duplicated checks which are done in some PMDs. Also, note that it is
behaviour change for some PMDs which simply ignore (with
error/warning log
message) unsupported VLAN offloads, but now it will fail.
Fixes: a4996bd89c42 ("ethdev: new Rx/Tx offloads API")

v3 -> v4: Delete "next_mask" label and modify the function that
when the
offload is not supported the function fail.
v2 -> v3: Add __rte_unused to avoid unused parameter 'dev' and 'mask'
warning.
v1 -> v2: Cleanup duplicated checks which are done in some PMDs.
