[U-Boot] [PATCH 1/2] remove unnecessary code in ata_piix

[Marek Vasut]

Dear Pavel Herrmann,

I think that code is valid. It configures the sata_curr_device to valid value in 
case this was not called from the context of the command. No?

I think it can be pulled from the loops above the return 0 though.
