    debugtrace: fix buffer allocation
    
    Commit 6338c9ead9ff9ef6 ("debugtrace: add per-cpu buffer option") had
    a rebase error when using per-cpu buffers: the global buffer address
    would always be set to the one of the last per-cpu buffer allocated.
    
    The result would be that when dumping the buffers the last cpu's buffer
    is always shown as empty as those entries are printed in the global
    buffer's dump already.
    
    Fix that.
