ata: libata-core: Set capacity to zero for a security locked drive

For Security locked drives (drives that have Security enabled, and have
not been Security unlocked by boot firmware), the automatic partition
scanning will result in the user being spammed with errors such as:

  ata5.00: failed command: READ DMA
  ata5.00: cmd c8/00:08:00:00:00/00:00:00:00:00/e0 tag 7 dma 4096 in
           res 51/04:08:00:00:00/00:00:00:00:00/e0 Emask 0x1 (device error)
  ata5.00: status: { DRDY ERR }
  ata5.00: error: { ABRT }
  sd 4:0:0:0: [sda] tag#7 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK cmd_age=0s
  sd 4:0:0:0: [sda] tag#7 Sense Key : Aborted Command [current]
  sd 4:0:0:0: [sda] tag#7 Add. Sense: No additional sense information

during boot, because most commands except for IDENTIFY will be aborted by
a Security locked drive.

For a Security locked drive, set capacity to zero, so that no automatic
partition scanning will happen.

If the user later unlocks the drive using e.g. hdparm, the close() by the
user space application should trigger a revalidation of the drive.
