Subject: [PATCH 30/41] scsi: megaraid_sas_fusion: Mark expected switch
 fall-through

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

Notice that, in this particular case, I replaced "Fall thru" with a
"Fall through" annotation and added a dash as a token in order to
separate the "Fall through" annotation from the rest of the comment
on the same line, which is what GCC is expecting to find.
