vppinfra: prevent dlmalloc from allocating memory via mmap_alloc()
If the heap does not have enough space to satisfy allocation
request, the allocator calls sys_alloc(). There, if the request
is bigger than mparams.mmap_threshold, the mmap_alloc() is called
to allocate memory via a direct mmap call.
The resulting allocated memory is properly recognized by
clib_mem_is_heap_object() only for the first such request.
Subsequent requests overwrite the tracking data, resulting
in previously "valid" addresses become invalid, as seen
by clib_mem_is_heap_object(). The result is a misleading
behavior which masks other issues.
This is a temporary change to avoid the affected codepath
until there is a proper fix to track the directly mmap-allocated
memory.
