bnxt_en: Support QOS and TPID settings for the SRIOV VLAN

With recent changes in the .ndo_set_vf_*() guidelines, resubmitting
this patch that was reverted eariler in 2023:

c27153682e ("Revert "bnxt_en: Support QOS and TPID settings for the SRIOV VLAN")

Add these missing settings in the .ndo_set_vf_vlan() method.
Older firmware does not support the TPID setting so check for
proper support.

Remove the unused BNXT_VF_QOS flag.
