scsi: aacraid: fix leak of data from stack back to userspace
The fields sense_data_size and sense_data are unitialized garbage from
the stack and are being copied back to userspace. Fix this leak of
stack information by ensuring they are zero'd.
Detected by CoverityScan, CID#1435473 ("Uninitialized scalar variable")
Fixes: 423400e64d377 ("scsi: aacraid: Include HBA direct interface")
