Avoid Android's CFI feature induced crash at runtime in audio flinger's effects chain.

Summary:
An occasional crash is observed while exercising special effects
suspend session.
A feature checks for strict function pointer types at runtime on
static analysis of conditional code path, and if it finds a
violation, it induces a crash. This fix separates the two
steps and avoids a null object dereferencing.
