[PATCH] namdev: allow symlink-only rules to specify node permissions

First case without the patch:
KERNEL="hd*", GROUP="disk", MODE="0660"
KERNEL="hdc", SYMLINK="cdrecorder", MODE="0666"
brw-rw----  1 root disk 22, 0 Feb  5 14:08 /dev/hdc

Second case without the patch:
KERNEL="hd*", GROUP="disk", MODE="0660"
KERNEL="hdc", MODE="0666"
brw-rw-rw-  1 root disk 22, 0 Feb  5 14:08 /dev/hdc
