Fix AIBinder_setMinSchedulerPolicy failed to set sched policy

b/318477176

the first param of:
AIBinder_setMinSchedulerPolicy(mAidlComposerCallback->asBinder().get(), SCHED_FIFO, 2);

constructs a temprary SpAIBinder object, it destructed after this function called.
and destroyed the `BBinder` object. got this log printted:
01-03 06:04:25.884  3774  3774 W surfaceflinger: Binder 0xf3b821dc destroyed after setMinSchedulerPolicy before being parceled.

This CL can fix this issue, and the scheduler works as expected.
