If the main thread was interrupted during
ExoPlayerImplInternal.blockingSendMessage/release, the interrupted flag was
immediately set but then wait() was called on the next iteration. wait() would
immediately throw InterruptedException, causing the main thread to spin until
the blocking operation completed.
Instead of resetting the flag immediately, reset it after the blocking
operation completes.
