[Bugfix] [2.6.35-rc3-tip] perf build failure on latest tip.

[Bugfix] [2.6.35-rc3-tip] perf build failure on latest tip.

[Srikar Dronamraju]

When compiling perf on latest tip/master
I see the following error

cc1: warnings being treated as errors
util/newt.c: In function ‘hist_entry__tui_annotate’:
util/newt.c:764: warning: ‘ret’ is used uninitialized in this function
make: *** [util/newt.o] Error 1

I think the problem was introduced by commit 
13f499f076c67675e6e3022973729b5d906a84e9

Below is a patch that fixes the problem.
