[libvirt] [PATCH 1/2] libxl: honor autoballoon setting in libxl.conf

libxlGetAutoballoonConf is supposed to honor user-specified autoballoon setting in libxl.conf. As written, the user-specified setting could be overwritten by the subsequent logic to check dom0_mem parameter. If user-specified setting is present and correct, accept it. Only fallback to checking Xen dom0_mem command line parameter if user-specfied setting is not present.
