Check return value of nand_read_data_op.
Notice that, currently, all instances of nand_read_data_op() are
being checked, with the exception of two of them in marvell_nand
driver, in which the caller function explicitly returns 0 every
time.
Also, notice that I moved the declaration of *ret* to the top of
fsmc_read_page_hwecc().
