nrf9160 example "modem_tcp_client.rs" crashes on nrf9151

Error:

TRACE ipc 2

By removing line 348 assert_eq!(rx_data_len, LIST_LEN); the example works 👍 .

With nrf9151 the rx_data_len at line 348 is 32 instead of 16 (which is LIST_LEN).

In that case, I think we should probably introduce some features on the net-nrf91 crate to configure both the correct pac crate, as well as the appropriate constants. Thanks for testing it out!

I think there's no guarantee the list size will stay constant in the future. Maybe we should make it a non-constant.

Also I think the list sizes don't have to match in both directions. We can make our list size a constant in the app->modem direction, and trust the modem's size for the modem->app direction (or maybe they're the other way around, not sure)
