ata-disk.c:ad_init(): max_iosize might be uninitialized?

[Mikolaj Golub]

Hi,

It might be a wrong list but I have not found freebsd-ata@ or freebsd-disk@
list -).

I just have looked accidentally at ad_init() in dev/ata/ata-disk.c and it
looks like there is at least theoretical possibility that atadev->max_iosize
remains uninitialized (if ata_controlcmd(ATA_SET_MULTI) fails). Shouldn't be
like in the patch below?
