[PATCH] powerpc/xmon: avoid warnings about variables that might be clobbered by ‘longjmp’

[Mathieu Malaterre]

Move initialization of variables after data definitions. This silence
warnings treated as error with W=1:

  arch/powerpc/xmon/xmon.c:3389:14: error: variable ‘name’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
  arch/powerpc/xmon/xmon.c:3100:22: error: variable ‘tsk’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
