v4:
* Patch 1 is following Markus's suggestion that remove the dead error
  handling.
* Patch 2 is separate from patch 1 to plug the memory leak in the v3.
* Patch 3 is based on the patch 1 in the v3. Meanwhile, dorp the superfluous
  prefix "rocker:" and adjust the commit message.

v3:
* Following Jason's suggstion that add suitable error message to 
  each error site.
* Modified the commit message to make it easier to read.

v2:
* Following Philippe's suggestion that shorten the patch subject 
  "hw/net/rocker/rocker" to "net/rocker". 
* Use a consistent log format to report error message.
* Add a specific goto label "err_name_too_long" to make a correct
  cleanup.
