[PATCH 06/11] btrfs-progs: use calloc instead of malloc+memset for extent_io.c

[Silvio Fricke <silvio.fricke@xxxxxxxxx>]

This patch is generated from a coccinelle semantic patch:

	identifier t;
	expression e;
	statement s;
	@@
	-t = malloc(e);
	+t = calloc(1, e);
	(
	if (!t) s
	|
	if (t == NULL) s
	|
	)
	-memset(t, 0, e);
