fix "Missing break in switch" coverity reports
Many of these are marked as "intentional/fix required" because they just need adding a fall through comment. This is exactly what this patch does, except for target/mips/translate.c where it is easier to duplicate the code, and hw/audio/sb16.c where I consulted the DOSBox sources and decide to just remove the LOG_UNIMP before the fallthrough.
