Md Sadre Alam ae38a196ca driver: nand: qpic_nand: Fix NULL pointer dereference. 
This change will fix NULL pointer dereference while reading
from spi nand flash in oobbuf.

The multipage read features is only to read with ecc for
raw read/write the the access is page wise due to mtd layer
will request only one page at a time. So don't increment oobbuf
for every page while reading if already bitflips are present in spi
nand flash. if so data abort will happen due to NULL pointer
dereference.

error:
NAND read: device 0 offset 0x4480000, size 0x1000
data abort
