universal7885: parts-aidl: Unlock mutex if try_lock() returned true

try_lock() returns instantly, but it does acquires mutex lock if it is avaliable. If we just return try_lock() result, mutex is still locked by the thread. So it results in forever false with try_lock(). If the try_lock() returns true, unlock and return true for fix
