qed: Mark expected switch fall-through

GustavoARSilva · davem330 · commit ed35da4fce1d · 2019-01-23T09:06:36.000-08:00
In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

This patch fixes the following warning:

drivers/net/ethernet/qlogic/qed/qed_cxt.c:2126:4: warning: this statement may fall through [-Wimplicit-fallthrough=]

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.
