strparser: Don't schedule in workqueue in paused state
In function strp_data_ready(), it is useless to call queue_work if the state of strparser is already paused. The state checking should be done before calling queue_work. The change reduces the context switches and improves the ktls-rx throughput by approx 20% (measured on cortex-a53 based platform).
