[PATCH] drm/radeon/evergreen_cs: fix missing break in switch statement

[Gustavo A. R. Silva]

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

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

Fixes: dd220a00e8bd ("drm/radeon/kms: add support for streamout v7")
Cc: stable@vger.kernel.org
Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com>

NOTE: Notice that this code has been out there since 2012. So, it
would be helpful if someone can double-check this.
