scsi: aha1740: Avoid over-read of sense buffer
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. SCtmp->sense_buffer is 96 bytes, but ecbptr->sense is 14 bytes. Instead of over-reading ecbptr->sense, copy only the actual contents and zero pad the remaining bytes, avoiding potential over-reads.
