Unhandled EZSP frame incomingManyToOneRouteRequestHandler and OTA update in progress causes EZSP to stop

[irata-coder]

What happened?

Unhandled EZSP frame incomingManyToOneRouteRequestHandler while performing an OTA update of another device, causes EZSP to stop

This recreates the issue always, although I beleive the root cause is when resending data frames, around the code which queues/waits for messages. I believe there has been changes to this code recently, as this error is recent. When network traffic is busy it appears to trigger a bug in the code, albeit I can't yet see why.

What did you expect to happen?

Receipt of this frame should not cause EZSP and driver to stop

How to reproduce it (minimal and precise)

1.) Create a Zigbee network with z2m and sonoff ZBDongle-E with 7.3.2.0 build 212 (albeit also recreatable on earlier builds)
2.) Add Hive 1613V Active Plug and Bosch BTH-RA
3.) Start an OTA update on Bosch BTH-RA
4.) Within a few minutes, this frame will arrive and the error is seen, stopping the driver
