audioflinger: fix pre processing transfer between record threads.
Fix two problems remaining with pre processing effects transfer from
one record thread to the next in case of tear down due to device connection:
1 - the enabled state of the effects was not communicated to the new HAL
input stream.
2 - the effects saved in orphan chains list were not transfered to the
new thread when a AudioRecord was created.
Bug: 17757378.
