Fix AAudio waiting for stop SIGABRT
WaitForStateChange is a function that notifies the user if the
state moves from a specific state. When the state moves to closed,
however, a SIGABRT is thrown because waitForStateChange is in a
deleted pointer.
android::sp has a property where casting an instance to a sp increments
the usage count by 1. Thus, by adding casting the AAudioStream to a sp,
the AAudioStream is no longer deleted when the stream closes. With this
change, the SIGABRT is no longer thrown.
Bug: 63089499
Test: Ran new wait_for_state_change_closed with and without change.
Verified that the test fails before the cl and the test now passes
after the change.
