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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
