commit 40412e3c99722229f1ec93cd95fc8486d778f5df

    libxl: Fix bootloader-related virtual memory leak on pv build failure
    
    The bootloader may call libxl__file_reference_map(), which mmap's the
    pv_kernel and pv_ramdisk into process memory.  This was only unmapped,
    however, on the success path of libxl__build_pv().  If there were a
    failure anywhere between libxl_bootloader.c:parse_bootloader_result()
    and the end of libxl__build_pv(), the calls to
    libxl__file_reference_unmap() would be skipped, leaking the mapped
    virtual memory.
    
    Ideally this would be fixed by adding the unmap calls to the
    destruction path for libxl__domain_build_state.  Unfortunately the
    lifetime of the libxl__domain_build_state is opaque, and it doesn't
    have a proper destruction path.  But, the only thing in it that isn't
    from the gc are these bootloader references, and they are only ever
    set for one libxl__domain_build_state, the one which is
    libxl__domain_create_state.build_state.
    
    So we can clean up in the exit path from libxl__domain_create_*, which
    always comes through domcreate_complete.
    
    Remove the now-redundant unmaps in libxl__build_pv's success path.
    
    This is XSA-160.
