Subject: [PATCH] soc: fsl: dpio: fix kcalloc() argument order

From: Arnd Bergmann <arnd@...db.de>

A previous bugfix added a call to kcalloc(), which starting in gcc-14
causes a harmless warning about the argument order:

drivers/soc/fsl/dpio/dpio-service.c: In function 'dpaa2_io_service_enqueue_multiple_desc_fq':
drivers/soc/fsl/dpio/dpio-service.c:526:29: error: 'kcalloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
  526 |         ed = kcalloc(sizeof(struct qbman_eq_desc), 32, GFP_KERNEL);
      |                             ^~~~~~
drivers/soc/fsl/dpio/dpio-service.c:526:29: note: earlier argument should specify number of elements, later size of each element

Since the two are only multiplied, the order does not change the
behavior, so just fix it now to shut up the compiler warning.

Fixes: 5c4a5999b245 ("soc: fsl: dpio: avoid stack usage warning")
