[PATCH] x86/resctrl: Slightly clean-up mbm_config_show()

From: Christophe JAILLET
Date: Sat Jul 13 2024 - 07:04:02 EST


'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
