mgmt: mcumgr: transport: dummy: Fix issue with large packets

nordicjm · fabiobaltieri · commit 5d8c79f064fe · 2022-12-07T13:53:02.000Z
Fixes an issue with large packets being received, these packets are
chunked into 127-byte frames for the serial transport but this system
is not needed for the dummy transport as it has a fixed size buffer.
