[Xen-devel] [PATCH v3] xl: log an error if libxl_cpupool_destroy() fails

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

In fact, right now, failing at destroying a cpupool is just
not reported to the user in any explicit way.

Let's log an error, as it is customary for xl in these cases.

Changes from v2:
 * rebased on top of staging;
 * fixed Juergen's email address

Changes from v1:
 * avoid changing the return code to EXIT_SUCCESS/FAILURE;
   that is being taken care of in another series anyway.
