mtd: spi-nor: Fix mtd size for s3an flashes 



As it was before the blamed commit, s3an_nor_scan() was called
after mtd size was set with params->size, and it overwrote the mtd
size value with '8 * nor->page_size * nor->info->n_sectors' when
XSR_PAGESIZE was set. With the introduction of
s3an_post_sfdp_fixups(), we missed to update the mtd size for the
s3an flashes. Fix the mtd size by updating both nor->params->size,
(which will update the mtd_info size later on) and nor->mtd.size
(which is used in spi_nor_set_addr_width()).
