When removing a range of VLANs in which PVID is a member we should use
the correct PVID value instead of some VLAN in the range.
Also, change two print statements to use 'dev' instead of
'mlxsw_sp_port->dev', as it's already used in other print statements in
the function.

When adding or deleting VLANs from a bridged port, HW VLAN filters must be
set accordingly. Instead of having the same code in both add and delete
functions, just wrap it in a function and call it with the appropriate
parameters.

The operation of adding VLANs on a port via switchdev ops can fail and
we need to be prepared for it. If we do not rollback hardware operations
following a failure, hardware and software will remain in an
inconsistent state.
Solve that by adding suitable error paths to __mlxsw_sp_port_vlans_add.
