mtd: cafe_nand: fix an & vs | mistake
commit 48f8b641297df49021093763a3271119a84990a2 upstream. 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.
