'vlan_bitmap' is a bitmap and is used as such. So allocate it with
devm_bitmap_zalloc() and its explicit bit size (i.e. VLAN_N_VID).
This avoids the need of the VLAN_BITMAP_SIZE macro which:
- needlessly has a 'nic_dev' parameter
- should be "long" (and not byte) aligned, so that the bitmap semantic
is respected
This is in fact not an issue because VLAN_N_VID is 4096 at the time
being, but devm_bitmap_zalloc() is less verbose and easier to understand.
