Revert "xen: Allow to undefine a running domain (xm_internal)"
Revert "xen: Allow to undefine a running domain (xm_internal)"

ACK was given too soon.  According to the code, the xm driver is
only used for inactive domains, and has no notion of an active
domain, thus, it cannot support undefine of a running domain.
The real fix for xen needs to be in the unified driver and/or
the xend level.

This reverts commit 49186deda62161599877b0de6f7f4345c50d842a.
