x86/crash: Add a forward declaration of struct kimage

Browse Source 
Add a forward declaration of struct kimage to the crash.h header because
future changes will invoke a crash-specific function from the realmode
init path and the compiler will complain otherwise like this:

  In file included from arch/x86/realmode/init.c:11:
  ./arch/x86/include/asm/crash.h:5:32: warning: ‘struct kimage’ declared inside\
   parameter list will not be visible outside of this definition or declaration
      5 | int crash_load_segments(struct kimage *image);
        |                                ^~~~~~
  ./arch/x86/include/asm/crash.h:6:37: warning: ‘struct kimage’ declared inside\
   parameter list will not be visible outside of this definition or declaration
      6 | int crash_copy_backup_region(struct kimage *image);
        |                                     ^~~~~~
  ./arch/x86/include/asm/crash.h:7:39: warning: ‘struct kimage’ declared inside\
   parameter list will not be visible outside of this definition or declaration
      7 | int crash_setup_memmap_entries(struct kimage *image,
        |
