Gaurav Singh d909f9db0c bpf, xdp, samples: Fix null pointer dereference in *_user code
[ Upstream commit 6903cdae9f ]

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().

Fixes: 0fca931a6f ("samples/bpf: program demonstrating access to xdp_rxq_info")
