Subject: [PATCH 24/41] scsi: lpfc: lpfc_hbadisc: 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" with a
"fall through" annotation, which is what GCC is expecting to find.
