[PATCH] paride_register(): shuffle return values

paride_register() returns 1 on success, 0 on failure and module init
code looks like

	static int __init foo_init(void)
	{
		return paride_register(&foo) - 1;
	}

which is not what one get used to. Converted to usual 0/-E convention.

In case of kbic driver, unwind registration. It was just

	return (paride_register(&k951)||paride_register(&k971))-1;
