KVM: selftests: Fix transposed calloc() arguments in the uffd helper

uffd_setup_demand_paging() passes the element size as the first argument
to calloc() and the element count as the second:

	uffd_desc->pipefds = calloc(sizeof(int), num_readers);

calloc() expects the number of elements first and the size of each element
second. The product, and therefore the allocation size, is the same either
way, so this is not a functional change, but the arguments are misleading
and GCC 14 diagnoses them with -Wcalloc-transposed-args, which is enabled
by -Wextra.

Swap the arguments to match the calloc() prototype.
