[PATCH net-next 4/4] rocker: make rocker_port_internal_vlan_id_{get,put}() non-transactional

[Simon Horman <simon.horman@netronome.com>]

The motivation for this is that rocker_port_internal_vlan_id_{get,put} appear
to only partially implement the transaction model: memory allocation
and freeing is transactional, but hash and bitmap manipulation is not.

The latter could be fixed, however, as it is not currently exercised
due to trans always being SWITCHDEV_TRANS_NONE it seems cleaner
to make rocker_port_internal_vlan_id_get non-transactional.

Found by inspection.
I do not believe that this change should have any run-time effect.

Fixes: c4f20321d968 ("rocker: support prepare-commit transaction model")
