arm_mpam: On saving mbwu state read the monitors before clearing CFG_MBWU_CTL
In mpam_save_mbwu_state() the monitor values are read using __ris_msmon_read_locked()
which checks if the configuration provided matches that in the hardware and if
not then resets the monitor. To avoid resetting the monitor before reading the
value that needs saving only clear the configuration after the monitor is read.
