libata: Set max sector to 65535 for Slimtype DVD A DS8A8SH drive

The Slimtype DVD A  DS8A8SH drive locks up when max sector is smaller than
65535, and the blow backtrace is observed on locking up:

 The above trace was triggered by
   "dd if=/dev/zero of=/dev/sr0 bs=2048 count=32768"

 It was previously working by accident, since another bug introduced
 by 4dce8ba94c7 (libata: Use 'bool' return value for ata_id_XXX) caused
 all drives to use maxsect=65535.
