powerpc/kgdb: Fix build failure caused by "kgdb.c: unused variable 'acc'"

'acc' isn't used anywhere and thus triggers gcc warning, which causes
build error with CONFIG_PPC_DISABLE_WERROR=n (default):

  cc1: warnings being treated as errors
  arch/powerpc/kernel/kgdb.c: In function 'gdb_regs_to_pt_regs':
  arch/powerpc/kernel/kgdb.c:289: warning: unused variable 'acc'
  make[1]: *** [arch/powerpc/kernel/kgdb.o] Error 1
