Kohei Tarumizu 499c8bb469 x86/resctrl: Fix to restore to original value when re-enabling hardware prefetch register
The current pseudo_lock.c code overwrites the value of the
MSR_MISC_FEATURE_CONTROL to 0 even if the original value is not 0.
Therefore, modify it to save and restore the original values.

Fixes: 443810fe61 ("x86/intel_rdt: Create debugfs files for pseudo-locking testing")
