[PATCH 01/11] btrfs-progs: use calloc instead of malloc+memset for btrfs-image.c

[Silvio Fricke]

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);
