If mkdir_mondata_all() or a subsequent call in rdt_get_tree() fails, the
mon_data structures allocated by mon_get_kn_priv() are leaked.
Add mon_put_kn_priv() to the out_mongrp error path to free the mon_data
structures.
Fixes: 2a65660385 ("x86/resctrl: Expand the width of domid by replacing mon_data_bits")
