kernel: debug: Fix unreachable code in gdb_serial_stub() 

Fix the following warning:

kernel/debug/gdbstub.c:1049:4: warning: fallthrough annotation in unreachable code [-Wimplicit-fallthrough]
                           fallthrough;
                           ^
   include/linux/compiler_attributes.h:210:41: note: expanded from macro 'fallthrough'
   # define fallthrough                    __attribute__((__fallthrough__)

by placing the fallthrough; statement inside ifdeffery.
