libata: Fixup n_elem initialization
Fixup the inialization of qc->n_elem. It currently gets initialized to 1 for commands that do not transfer any data. Fix this by initializing n_elem to 0 and only setting to 1 in ata_scsi_qc_new when there is data to transfer. This fixes some problems seen with SATA devices attached to ipr adapters.
