[PATCH 6.1 60/64] vhost: use kzalloc() instead of kmalloc() followed by memset()

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Prathu Baronia <redacted>

commit 4d8df0f5f79f747d75a7d356d9b9ea40a4e4c8a9 upstream.

Use kzalloc() to allocate new zeroed out msg node instead of
memsetting a node allocated with kmalloc().
