CodecOutputList should be recycled in a finally block (#10186)

Browse Source 
Motivation:

To ensure we always recycle the CodecOutputList we should better do it in a finally block

Modifications:

Call CodecOutputList.recycle() in finally

Result:

Less chances of non-recycled lists. Related to https://github.com/netty/netty/issues/10183
