alloc_exit_info() calls kcalloc() but puts in the size of the element as the
first argument which triggers the following gcc warning:

kernel/sched/ext.c:3815:32: warning: ‘kmalloc_array_noprof’ sizes
specified with ‘sizeof’ in the earlier argument and not in the later
argument [-Wcalloc-transposed-args]

Fix it by swapping the positions of the first two arguments. No functional
changes.
