Subject: [PATCH 19/41] scsi: isci: remote_node_context: mark expected switch
 fall-throughs

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

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