[PATCH v2] drm: radeon: add a missing break in evergreen_cs_handle_reg

[Mathieu Malaterre]

In commit dd220a00e8bd ("drm/radeon/kms: add support for streamout v7")
case statements were added without a terminating break statement. This
commit adds the missing break. This was discovered during a compilation
with W=1.

This commit removes the following warning:

  drivers/gpu/drm/radeon/evergreen_cs.c:1301:11: warning: this statement may fall through [-Wimplicit-fallthrough=]
