hal: Move sequence of audio_extn_auto_hal_open_input_stream

* Move the call sequence of audio_extn_auto_hal_open_input_stream
to avoid overriding the usecase field of struct stream_in
* This will fix the issue where adev->pcm_record_uc_state
won't be assign back to 1 in adev_close_input_stream
* CRs-Fixed: 2853209
