    libxl: avoid crashing if calling `virsh numatune' on inactive domain
    
    by, in libxlDomainGetNumaParameters(), calling libxl_bitmap_init() as soon as
    possible, which avoids getting to 'cleanup:', where libxl_bitmap_dispose()
    happens, without having initialized the nodemap, and hence crashing after some
    invalid free()-s:
