scsi: Protect against buffer possible overflow in scsi_set_sense_information

Make sure that the input sense buffer has sufficient length
to fit the information descriptor (12 additional bytes).
Modify scsi_set_sense_information to receive the sense buffer
length and adjust its callers scsi target and libata.

(Fix patch fuzz in scsi_set_sense_information - nab)
