Subject[PATCH 28/41] scsi: lpfc: lpfc_sli: 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, I replaced "Drop thru" and
"Fall Thru" with "fall through" annotations, which is what GCC
is expecting to find.

Also, in some cases 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.
