node_device: Do not lock the driver state needlessly
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.
