mtd: cafe_nand: fix an & vs | mistake
The intent here was clearly to set result to true if the 0x40000000 flag
was set. But instead there was a | vs & typo and we always set result
to true.
Artem: check the spec at
wiki.laptop.org/images/5/5c/88ALP01_Datasheet_July_2007.pdf
and this fix looks correct.
