ioat: fix xor_idx_to_desc
For versions of the device that implement operation-types 0x87, 0x88 (IOAT_OP_XOR, IOAT_OP_XOR_VAL) this map determines whether a given source is located in the base or extended descriptor. Source addresses 6 through 8 require an extended descriptor, hence 0xe0, not 0xd0. No shipping hardware currently implements these operation types.
