iotrace: fix behaviour when buffer is full
Don't continue updating the offset when buffer is full. When the buffer size exhausts and there's no space left to write warn the user and update only the needed size and not both the offset and needed size. Add needed buffer size information in the iotrace command. Signed-off-by: Ramon Fried <ramon.fried@gmail.com>
