resource: pass configuration to nr_processing_units()
resource: pass configuration to nr_processing_units()

to address the FTBFS.

in cdb2909cfea256ae8854017ee24be5b1e162df87, nr_processing_units()
starts to accept an instance of configuration as its parameter, so we
should pass it to nr_processing_units() when calling this function.
