hw/sparc64/niagara: use int64_t for vdisk size to avoid truncation

Browse source 
blk_getlength() returns int64_t, but niagara_init() stored it in an int,
truncating the if=pflash virtual-ramdisk size for images >= 2 GiB. A ~4 GiB
image truncated to 0/negative, failed the `size > 0` check, and exit(1)'d
before the CPU ran, ending with:

  qemu-system-sparc64: could not load ram disk
