Abhishek Sahu 693d06dffb mtd: rawnand: fix return value check for bad block status ...

commit e9893e6fa9 upstream.

Positive return value from read_oob() is making false BAD
blocks. For some of the NAND controllers, OOB bytes will be
protected with ECC and read_oob() will return number of bitflips.
If there is any bitflip in ECC protected OOB bytes for BAD block
status page, then that block is getting treated as BAD.

Fixes: c120e75e0e ("mtd: nand: use read_oob() instead of cmdfunc() for bad block check")
