Avoid BinderProxy duplicate native registration

In case of an OOME, we would recycle the nativeData we just allocated,
even if the BinderProxy.getInstance() call got far enough to register
the allocation for automatic freeing. This could cause a duplicate
deallocation.

This changes the code to be much more careful about handling native
deallocation correctly in the exception case.

Bug: 72707270

Test: Build and boot master.
