nand: mxc: Use appropriate page number in syndrome functions
The syndrome functions should use the page number passed as argument instead of the page number saved upon NAND_CMD_READ0. This does not make any difference if the NAND_NO_AUTOINCR option is set, but otherwise this fixes accesses to the wrong pages.
