Subject: test/init-mem: zero the ringbuf memory
References: fix-test-crash
Patch-mainline: Submitted, #1293

This is a similar fix to commit 8100d7b5f862 (test/buf-ring-nommap: zero
the ringbuf memory). The same is needed for test/init-mem as it crashes
with MALLOC_PERTURB_=69 too.

So zero the ringbuf memory after posix_memalign() too.

Fixes #1291.
