kexec-bzimage64: fix sparse warnings

David Howells brought to my attention the mails generated by kbuild test
bot and following sparse warnings were present.  This patch fixes these
warnings.

  arch/x86/kernel/kexec-bzimage64.c:270:5: warning: symbol 'bzImage64_probe' was not declared. Should it be static?
  arch/x86/kernel/kexec-bzimage64.c:328:6: warning: symbol 'bzImage64_load' was not declared. Should it be static?
  arch/x86/kernel/kexec-bzimage64.c:517:5: warning: symbol 'bzImage64_cleanup' was not declared. Should it be static?
  arch/x86/kernel/kexec-bzimage64.c:531:5: warning: symbol 'bzImage64_verify_sig' was not declared. Should it be static?
  arch/x86/kernel/kexec-bzimage64.c:546:23: warning: symbol 'kexec_bzImage64_ops' was not declared. Should it be static?
