net: dsa: don't emit targeted cross-chip notifiers for MTU change
A cross-chip notifier with "targeted_match=true" is one that matches
only the local port of the switch that emitted it. In other words,
passing through the cross-chip notifier layer serves no purpose.
Eliminate this concept by calling directly ds->ops->port_change_mtu
instead of emitting a targeted cross-chip notifier. This leaves the
DSA_NOTIFIER_MTU event being emitted only for MTU updates on the CPU
port, which need to be reflected also across all DSA links.
