mlxsw: spectrum: Propagate extack further for bridge enslavements

The code that actually takes care of bridge offload introduces a few
more non-trivial constraints with regards to bridge enslavements.
Propagate extack there to indicate the reason.

$ ip link add link enp1s0np1 name enp1s0np1.20 type vlan id 20
$ ip link add name br0 type bridge
$ ip link set dev enp1s0np1.10 master br0
$ ip link set dev enp1s0np1.20 master br0
Error: spectrum: Can not bridge VLAN uppers of the same port.
