ssb: use "break" on default case to prevent warning

Having an empty default: case in a switch statement causes a warning
(when using Clang; I don't see the warning when using gcc),
so add a "break;" to the default case to prevent the warning:

drivers/ssb/main.c:1149:2: warning: label at end of compound statement is a C2x extension [-Wc2x-extensions]
