[CRD iOS] Fixing an infinite layout loop

On iOS 9, it seems the [self updateFABConstraintsAnimated:NO] call in
viewDidLayoutSubviews and [self layoutIfNeeded] call in
updateFABConstraintsAnimated causes an infinite layout loop, which
crashes the app right after the HostViewController appears due to
stack overflow.

This CL fixes this problem by removing the
updateFABConstraintsAnimated: call from viewDidLayoutSubviews.
