  gcc [1] generates warning [2] about calloc usage, because calloc
parameter order is wrong, fixing it by replacing parameters.

[1]
gcc (GCC) 14.0.1 20240124 (experimental)

[2]
Compiling C object lib/librte_dmadev.a.p/dmadev_rte_dmadev.c.o
../lib/dmadev/rte_dmadev.c: In function ‘dmadev_handle_dev_dump’:
../lib/dmadev/rte_dmadev.c:1033:29:
  warning: ‘calloc’ sizes specified with ‘sizeof’ in the earlier
  argument and not in the later argument [-Wcalloc-transposed-args]
 1033 |     buf = calloc(sizeof(char), RTE_TEL_MAX_SINGLE_STRING_LEN);
      |                         ^~~~
