Subject: [PATCH 27/41] scsi: lpfc: lpfc_scsi: 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
"fall through" annotations, which is what GCC is expecting to find.
