scsi: isci: request: 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, a dash is added 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.
