hw/nand.c: Fix nand erase operation
Usually, nand erase operation has only 2 or 3 address cycles.
We need to mask s->addr to zero unset stale high-order bytes in the nand address
before using it as the erase address.
This fixes the NAND erase operation in Linux.
[PC: Generalised to work for any number of address cycles rather than just 3]
