[common] use correct argument order for calloc

The signature for calloc is void *calloc(size_t num, size_t size), where num
is the number of elements to allocate, and size is the size. Therefore, to
allocate a single struct, we should pass 1 for num and the size of the struct
as size.

In some places, we use the opposite order, and we should flip it.
