Subject: [PATCH] scsi: mpt3sas: Add missing breaks in switch statements

Fix the following warnings by adding the proper missing breaks:

drivers/scsi/mpt3sas/mpt3sas_base.c: In function ‘_base_display_OEMs_branding’:
drivers/scsi/mpt3sas/mpt3sas_base.c:3548:4: warning: this statement may fall through [-Wimplicit-fallthrough=]
    switch (ioc->pdev->subsystem_device) {
    ^~~~~~
drivers/scsi/mpt3sas/mpt3sas_base.c:3566:3: note: here
   case MPI2_MFGPAGE_DEVID_SAS2308_2:
   ^~~~
drivers/scsi/mpt3sas/mpt3sas_base.c:3567:4: warning: this statement may fall through [-Wimplicit-fallthrough=]
    switch (ioc->pdev->subsystem_device) {

drivers/scsi/mpt3sas/mpt3sas_base.c:3601:3: note: here
   case MPI25_MFGPAGE_DEVID_SAS3008:
   ^~~~
drivers/scsi/mpt3sas/mpt3sas_base.c:3735:4: warning: this statement may fall through [-Wimplicit-fallthrough=]
    switch (ioc->pdev->subsystem_device) {
    ^~~~~~
drivers/scsi/mpt3sas/mpt3sas_base.c:3745:3: note: here
   case MPI2_MFGPAGE_DEVID_SAS2308_2:
   ^~~~
drivers/scsi/mpt3sas/mpt3sas_base.c:3746:4: warning: this statement may fall through [-Wimplicit-fallthrough=]
    switch (ioc->pdev->subsystem_device) {
    ^~~~~~
drivers/scsi/mpt3sas/mpt3sas_base.c:3768:3: note: here
   default:
   ^~~~~~~

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

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