If we do nand device 0 command in u-boot on a device that has NAND support enabled but no NAND chip, we can get data abort at least on omaps.

Fix the issue by replacing the check with nand_info[dev] as suggested by Scott Wood. The check for name existed before because before the array-to-pointer conversion there was no way to directly test nand_info[dev] for emptiness.
