EDD: enable symlinks to SCSI devices

Symlinks from /sys/firmware/edd/int13_dev8x/disc to the appropriate
SCSI discs were added a year ago, but disabled because the
scsi_bus list contained non-'scsi_device's at that time, which
could have lead to an improper pointer following. The SCSI
mid-layer has rectified this, so this code can be re-enabled
in edd.c once again.
