[PATCH] wdctl: remove -d option leftover

-d option was removed in commit f56338b43973 ("wdctl: allow to specify more
than one device"), but the optstring wasn't updated at that time and wdctl
can still accept the option halfway as below:

 $ wdctl -d
 wdctl: option requires an argument -- 'd'

whereas it should say:

 wdctl: invalid option -- 'd'

So update the optstring.

Fixes: f56338b43973 ("wdctl: allow to specify more than one device")
