x86/resctrl: Slightly clean-up mbm_config_show()

Browse Source 
'mon_info' is already zeroed in the list_for_each_entry() loop below.  There
is no need to explicitly initialize it here. It just wastes some space and
cycles.

Remove this un-needed code.

On a x86_64, with allmodconfig:

  Before:
  ======
     text	   data	    bss	    dec	    hex	filename
    74967	   5103	   1880	  81950	  1401e	arch/x86/kernel/cpu/resctrl/rdtgroup.o

  After:
  =====
     text	   data	    bss	    dec	    hex	filename
    74903	   5103	   1880	  81886	  13fde	arch/x86/kernel/cpu/resctrl/rdtgroup.o
