kernel: mtk_bmt: counteracting calloc-transposed-args compiler warning

For kernel 6.12 there is a warning causing an error:
drivers/mtd/nand/mtk_bmt_v2.c: In function 'mtk_bmt_get_mapping_mask':
drivers/mtd/nand/mtk_bmt_v2.c:307:31: error: 'kmalloc_array_noprof' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
  307 |         used = kcalloc(sizeof(unsigned long), BIT_WORD(bmtd.bmt_blk_idx) + 1, GFP_KERNEL);
      |                               ^~~~~~~~

Swapping the arguments solves the problem.
