[libvirt] [PATCH] libxl: Fix double-dispose of libxl domain config

[Jim Fehlig]

libxlBuildDomainConfig() was disposing the libxl_domain_config object
on error, only to have it disposed again by libxlBuildDomainConfig()'s
caller, which resulted in a segfault.  Leave disposing of the config
object to it's owner.
