scsi: reset cdrom tray statuses on scsi_disk_reset

Tray statuses should be also reset. Some guests may lock the tray and
right after resetting the guest it should be unlocked and closed. This
is done on power-on, reset and resume from suspend/hibernate on bare-metal.

This fix is already committed for IDE CD.
Check the commit a7f3d65b65.

Test results on bare-metal:
  - on reset/power-on the CD-ROM tray is closed even before the monitor
    is turned on
  - on resume from suspend/hibernate the tray is also closed before
    the monitor is turned on

From test results it seems that this behavior is OS and probably BIOS
independent.
