[Qemu-block] [PATCH] hw/block/nand: Fix bad offset in nand_blk_load for on-drive OOB |

The logic wants 512-byte aligned blk ops.
To switch to byte-based block accesses, the fixed commit changed the
blk read offset,
PAGE_START(addr) >> 9
with
PAGE_START(addr)
which min alignment, for on-drive OOB, is the min OOB size.
Consequently the reads are offset by PAGE_START(addr) & 0x1ff.
Fixes: 9fc0d361cc41 ("nand: Switch to byte-based block access")
