linux-user/mips/cpu_loop: silence the compiler warnings

Browse Source 
When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning:
linux-user/mips/cpu_loop.c: In function ‘cpu_loop’:
linux-user/mips/cpu_loop.c:104:24: warning: this statement may fall through [-Wimplicit-fallthrough=]

Add the corresponding "fall through" comment to fix it.
