ide: rename IDE_TFLAG_IN_[HOB_]FEATURE
The feature register has never been readable -- when its location is read, one gets the error register value; hence rename IDE_TFLAG_IN_[HOB_]FEATURE into IDE_TFLAG_IN_[HOB_]ERROR and introduce the 'hob_error' field into the 'struct ide_taskfile' (despite the error register not really depending on the HOB bit).
