[PATCH] libxl: Set current memory value after successful balloon

[Jim Fehlig <jfehlig@xxxxxxxx>]

The libxl driver does not set the new memory value in the active domain def
after a successful balloon. This results in the old memory value in
<currentMemory>. E.g.

virsh dumpxml test | grep currentMemory
  <currentMemory unit='KiB'>20971520</currentMemory>
virsh setmem test 16777216 --live
virsh dumpxml test | grep currentMemory
  <currentMemory unit='KiB'>20971520</currentMemory>

Set the new memory value in active domain def after a successful call to
libxl_set_memory_target().
