Converted vmalloc/memset and vmalloc_node/memset to
vzalloc or vzalloc_node using a cocci script and some editing

Reduces text a little bit.

Compiled x86 only.

There are still vmalloc_32 with memset calls still around.

Broken out to multiple patches to cc appropriate maintainers.

You may as well move the second s_flex_groups == NULL check inside the first one:

	if (sbi->s_flex_groups == NULL) {
		sbi->s_flex_groups = vzalloc(size);
		if (sbi->s_flex_groups == NULL) {
			ext4_msg(sb, KERN_ERR, "not enough memory for "
				 "%u flex groups", flex_group_count);
			goto failed;
		}
	}

Cheers, Andreas

differences from V1:
Andreas Dilger requested a block be moved so that
sbi->s_flex_groups isn't tested for NULL twice.
Also coalesced a ext4_msg printk format.
