When fall-through warnings was enabled by default the following warning
was starting to show up:

../drivers/gpu/drm/msm/adreno/adreno_gpu.c: In function ‘adreno_submit’:
../drivers/gpu/drm/msm/adreno/adreno_gpu.c:429:7: warning: this statement may fall
 through [-Wimplicit-fallthrough=]
    if (priv->lastctx == ctx)
       ^
../drivers/gpu/drm/msm/adreno/adreno_gpu.c:431:3: note: here
   case MSM_SUBMIT_CMD_BUF:
   ^~~~

Rework so that the compiler doesn't warn about fall-through.

Fixes: d93512ef0f0e ("Makefile: Globally enable fall-through warning")
