gst_omx_audio_dec_flush() causes a hang issue

Submitted by Jun Ji

Link to original bug (#743386)

Description

Simply I found that the newly added 'gst_pad_stop_task()' in gst_omx_audio_dec_flush() causes a hang issue when the this function is called seamlessly 10~20 times.

Once I remove the 'gst_pad_stop_task()', the hang issue isn't produced even with 100 consecutive flush().

Is it ok that I use this flush() function removed 'gst_pad_stop_task()' while I don't edit any other code in the latest gstreamer package?
