[SCSI] aic7xxx_old, eata_pio, ips, libsas: don't zero out sense_buffer in queuecommand



LLDs don't need to zero out scsi_cmnd::sense_buffer in queuecommand
since scsi-ml does. This is a preparation of the future changes to
allocate the sense_buffer only when necessary.

Many LLDs zero out the sense_buffer before touching it on the error
case. This patch lets them alone for now because new APIs for them
would be added later on.
