    bc: for_each_beancounter() definition for !CONFIG_BEANCOUNTERS
    
    This was found while tring to compile the kernel with a stock
    config (i.e. no CONFIG_BEANCOUNTERS, CONFIG_VE etc.) and
    boot it on IBM Power8.
    
    =============================================================
    
    Add for_each_beancounter() definition for !CONFIG_BEANCOUNTERS case,
    fixing the following compilation problem:
    
      CC      drivers/tty/sysrq.o
    drivers/tty/sysrq.c: In function ‘sysrq_handle_showmem’:
    drivers/tty/sysrq.c:320:2: error: implicit declaration of function
    ‘for_each_beancounter’ [-Werror=implicit-function-declaration]
      for_each_beancounter(ub)
      ^
    drivers/tty/sysrq.c:321:3: error: expected ‘;’ before ‘show_ub_mem’
       show_ub_mem(ub);
       ^
    cc1: some warnings being treated as errors
