[PATCH 4/8] xfs_repair: Fix free of uninit ptr in xfs_acl_valid() error path

[Eric Sandeen]

This error path:

xfs_acl_valid(xfs_acl_disk_t *daclp)
{
	xfs_acl_t	*aclp;
...
	if (daclp == NULL)
		goto acl_invalid;
...
acl_invalid:
	free(aclp);

attempts to free garbage; set it to NULL on init to make
it safe.
