x86/resctrl: Refactor resctrl_arch_rmid_read()
[ Upstream commit 7c9ac605e202c4668e441fc8146a993577131ca1 ]
resctrl_arch_rmid_read() adjusts the value obtained from MSR_IA32_QM_CTR to
account for the overflow for MBM events and apply counter scaling for all the
events. This logic is common to both reading an RMID and reading a hardware
counter directly.
Refactor the hardware value adjustment logic into get_corrected_val() to
prepare for support of reading a hardware counter.
