function-graph: allow unregistering twice
Impact: fix to permanent disabling of function graph tracer
There should be nothing to prevent a tracer from unregistering a
function graph callback more than once. This can simplify error paths.
But currently, the counter does not account for mulitple unregistering
of the function graph callback. If it happens, the function graph
tracer will be permanently disabled.
