Close acquire fence fd after camera capture
Camera capture should close acquire fence. If not, fd remains unused,
which consumes all available fd resources for a process (usually 1024).
Bug: 64214375
Test: Running camera preview of camera sample app for a long time
should not break preview image.
Exempt-From-Owner-Approval: This is a cherry-pick CL from oc-iot-dev.
