Avoid updating geometry restore after finishing move or resize

A while ago, geometryRestore() had to have a sane value even if the
window is not maximized because checkWorkspacePosition() used it.

Since checkWorkspacePosition() doesn't use geometryRestore() anymore, we
can stop updating the geometry restore.
