mpam/mpam_ctrlmon: update monitor config with its parent's ctrl_val 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I95A33


CVE: NA

----------------------------------------

When the monitor is created, the configuration should follow its parent's
configuration, instead of the last used configuration, or that would lead
to misconfiguration of monitor group.

Fixes: 08127bbf ("mpam: update monitor rmid and group configuration")
