sfc: mcdi_port: Mark expected switch fall-through
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/sfc/mcdi_port.c: In function ‘efx_mcdi_phy_decode_link’:
./include/linux/compiler.h:77:22: warning: this statement may fall through [-Wimplicit-fallthrough=]

-Wimplicit-fallthrough.
