Fix TextureView calling eglCreateImage with a destructed buffer

Fix an issue with hardware buffer passed from the SurfaceTexture
being destroyed before an SkImage is created. This CL is matched
by a change in frameworks/native
I2e025e683052168546f2e271a20a857b1e556b64.

Test: Ran TextureView CTS tests and a few apps that use TextureView.
Test: Fix verified by partner Mediatek
