bufferhubd: Fix an error on not closing post_fence explicitly.
There is a typo in the code that instead of calling close() on a Post
fence, actually did get_fd() which is really a no-op.
Fixed by changing the call to call() explicitly.
Bug: None
Test: `m -j32` succeeds. Sailfish boots, CubeSea works.
