target/ppc/excp_helper: Add a fallthrough for fix compiler warning
When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning:
../target/ppc/excp_helper.c: In function ‘powerpc_excp’:
../target/ppc/excp_helper.c:529:13: warning: this statement may fall through [-Wimplicit-fallthrough=]
529 | msr |= env->error_code;
| ~~~~^~~~~~~~~~~~~~~~~~
../target/ppc/excp_helper.c:530:5: note: here
530 | case POWERPC_EXCP_HDECR: /* Hypervisor decrementer exception */
| ^~~~
Add the corresponding "fall through" comment to fix it.
