Add missing break statement in order to prevent the code from falling
through to case CHIP_NAVI10.

This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.

Fixes: 14328aa58ce5 ("drm/amdkfd: Add navi10 support to amdkfd. (v3)")

By the way, Alex, I'm planning to add these fixes to my tree. I want
to send a pull-request to Linus for v5.3-rc2 this afternoon. We want
to have the -Wimplicit-fallthrough option globally enabled in v5.3,
and these are some of the last fall-through warnings remaining in
the kernel.

Can I have your Ack or Signed-off-by for all these drm patches?

Thanks!

I didn't realize you were sending these yourself. I was going to
include them in my upcoming -fixes pull.  Feel free to add my RB to
all three.
