When processing the PCI devices we can only read the configs for each of them if running as privileged. That information is saved in the driver state as a boolean introduced in commit 643c74abff01. However since that version it is only written to once during nodeStateInitialize() and only read from that point (apart from some commits around v3.9.0 release when it was not even set, but that was fixed before v3.10.0). And it is only read once, just to store that boolean in a temporary variable which is also used in only one condition. Rewrite this without locking and save few lines of code.
