[PATCH] linux/ioctlent.sh: handle multiple defines per-ioctl

The current sed statement works fine if the ioctl definition only utilizes
one define in it.  If it uses two, things fall apart.  Such is the case with
Only the last define (DM_LIST_DEVICES_CMD) gets extracted.  This tweaks the
sed to handle the two-define case.

I also fixed uniq/sort as doing `... | uniq | sort` wont work, you need to
reverse the steps for uniq to actually work.
