Consider the case where you have two chips side by side on the bus. One
completes and the other doesn't; your if() statement doesn't match that
but we still needed to restart the erase.

cfi_cmdset_0001.c issues an erase resume and then a status command, to
ensure that the chip goes into status mode even if it had previously
completed the erase.
