Patch to improve one minor ata status print during error situation

[Tony Frank]

Hi there,

Note this only applies to -STABLE as the error handling & status prints
have changed quite a bit when looking at -HEAD.

Currently I got this:

ad2s1e: hard error reading fsbn 32383 of 16160-16415 (ad2s1 bn 32383; cn 4 tn 34 sn 1)
ad2: success setting PIO4 on generic chip
 trying PIO mode
ad2: DMA problem fallback to PIO mode
ad2: DMA problem fallback to PIO mode
ad2: DMA problem fallback to PIO mode
ad2: DMA problem fallback to PIO mode
ad2: DMA problem fallback to PIO mode
ad2: DMA problem fallback to PIO mode
ad2: DMA problem fallback to PIO mode
ad2s1e: hard error reading fsbn 32495 of 16160-16415 (ad2s1 bn 32495; cn 4 tn 35 sn 50) status=59 error=01

With the attached patch it would show as:

ad2s1e: hard error reading fsbn 32383 of 16160-16415 (ad2s1 bn 32383; cn 4 tn 34 sn 1) trying PIO mode
ad2: success setting PIO4 on generic chip
ad2: DMA problem fallback to PIO mode

While not a big deal it may be simple enough to add?

Attached patch was created from:
 * $FreeBSD: src/sys/dev/ata/ata-disk.c,v 1.60.2.27 2003/09/05 18:27:38 dg Exp $

Regards,
