The pm_runtime_set_suspended() call in bcm_close() is intended as a counterpart to the pm_runtime_set_active() call from bcm_request_irq() (which gets called from bcm_setup()). The pm_runtime_set_active() call only happens if our pre-requisites for doing runtime-pm are met. This commit adds the same check to the pm_runtime_set_suspended() call to avoid the runtime-pm state getting stuck in suspended after after a bcm_close().
