Subject: x86/intel_rdt: Move pseudo_lock_region_clear()
Git-commit: ce730f1cc1255be152c879a2bc5f295d341d8036
Patch-mainline: v4.19-rc1
References: fate#324432

The pseudo_lock_region_clear() function is moved to earlier in the file in
preparation for its use in functions that currently appear before it. No
functional change.
