    libxl: fix libxl_set_memory_target
    
    Commit 26dbc93a ("libxl: Remove pointless hypercall from
    libxl_set_memory_target") removed the call to xc_domain_getinfolist, but
    it failed to notice that "info" was actually needed later.
    
    Put that back. While at it, make the code conform to coding style
    requirement.
