net: mvneta: Add missing hotplug notifier transition
The mvneta_percpu_notifier() hotplug callback lacks handling of the
CPU_DOWN_FAILED case. That means, if CPU_DOWN_PREPARE failes, the
driver is not well configured on the CPU.
Add handling for CPU_DOWN_FAILED[_FROZEN] hotplug notifier transition
to setup the driver.
