bpf, xdp, samples: Fix null pointer dereference in *_user code
[ Upstream commit 6903cdae9f9f08d61e49c16cbef11c293e33a615 ]
Memset on the pointer right after malloc can cause a NULL pointer
deference if it failed to allocate memory. A simple fix is to
replace malloc()/memset() pair with a simple call to calloc().
