perf top: Fix top.call-graph config option reading 

[ Upstream commit a3a4a3b37c ]

When trying to add the "call-graph" variable for top into the
.perfconfig file, like:

      [top]
            call-graph = fp

I that perf_top_config() do not parse this variable.

Fix it by calling perf_default_config() when the top.call-graph variable
is set.
