mtd: core: initialize *retlen in mtd_write()

Some mtd drivers like the spi-nor driver do not assign a value
to the retlen pointer but instead only add the bytes written
to *retlen. Users of mtd_write expect the variable to be initialized
by the mtd core though, so we have to do it in mtd_write(). The
same is done in mtd_read already.
