[PATCH 02/16] efi/riscv: libstub: Don't set image_size in handle_kernel_image()

[Jason Gunthorpe]

Sashiko points out the image_size should only be set if image_addr was
reassigned to some allocated memory. If image_size is not zero then the
caller will free the image_addr pointer.

efi_kaslr_relocate_kernel() never works like that, if it changes
image_addr to allocated memory the free is done through reserve_size.
