mtd: nand: fix error handling in nand_prog_page_op() #1
On success chip->legacy.waitfunc() returns the NAND status byte, but on failure it returns a negative error code. This was never tested for and instead the return value was interpreted as NAND status without error checking. Add the missing error check.
