skd: remove broken discard support
Simply creating a file system on an skd device, followed by mount and
fstrim will result in errors in the logs and then a BUG(). Let's remove
discard support from that driver. As far as I can tell, it hasn't
worked right since it was merged. This patch also has a side-effect of
cleaning up an unintentional shadowed declaration inside of
skd_end_request.
I tested to ensure that I can still do I/O to the device using xfstests
./check -g quick. I didn't do anything more extensive than that,
though.
