Subject: [PATCH][next] scsi: mpt3sas: Fix fall-through warnings for Clang

In preparation to enable -Wimplicit-fallthrough for Clang, fix a couple
of warnings by explicitly adding break statements instead of just letting
the code fall through to the next case.

JFYI: We had thousands of these sorts of warnings and now we are down
      to just 25 in linux-next. These are some of those last remaining
      warnings.
