mtd: nand: make reads using MTD_OOB_RAW affect only ECC validation
This changes the behavier of MTD_OOB_RAW. It used to read both OOB and
data to the data buffer, however you would still need to specify the
dummy oob buffer.
This is only used in one place, but makes it hard to read data+oob
without ECC test, thus I removed that behavier, and fixed the user.
Now MTD_OOB_RAW behaves just like MTD_OOB_PLACE, but doesn't do ECC
validation
