promisor-remote: fix xcalloc() argument order
Pass the number of elements first and their size second, as expected
by xcalloc().
Patch generated with:
make SPATCH_FLAGS=--recursive-includes contrib/coccinelle/xcalloc.cocci.patch
Our default SPATCH_FLAGS ('--all-includes') doesn't catch this
transformation by default, unless used in combination with a large-ish
SPATCH_BATCH_SIZE which happens to put 'promisor-remote.c' with a file
that includes 'repository.h' directly in the same batch.
