staging: comedi: ni_660x: fix missing break in switch statement
commit 479826cc86118e0d87e5cefb3df5b748e0480924 upstream.
Add missing break statement in order to prevent the code from falling
through to the default case and return -EINVAL every time.
This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.
