ice: Fix error with handling of bonding MTU
When a bonded interface is destroyed, .ndo_change_mtu can be called
during the tear-down process while the RTNL lock is held. This is a
problem since the auxiliary driver linked to the LAN driver needs to be
notified of the MTU change, and this requires grabbing a device_lock on
the auxiliary_device's dev. Currently this is being attempted in the
same execution context as the call to .ndo_change_mtu which is causing a
dead-lock.
Move the notification of the changed MTU to a separate execution context
(watchdog service task) and eliminate the "before" notification.
