libxl: remove libxlVmReap function

This function, which only has five call sites, simply calls
libxl_domain_destroy and libxlVmCleanup.  Call those functions
directly at the call sites, allowing more control over how a
domain is destroyed and cleaned up.  This patch maintains the
existing semantic, leaving changes to a subsequent patch.
