[SUNGEM]: Fix NAPI regression with reset work
sungem's gem_reset_task() will unconditionally try to disable NAPI even when it's called while the interface is not operating and hence the NAPI struct isn't enabled. Make napi_disable() depend on gp->running. Also removes a superfluous test of gp->running in the same function.
