tracing: fix double free
clang static analyzer reports this problem
trace_events_hist.c:3824:3: warning: Attempt to free
released memory
kfree(hist_data->attrs->var_defs.name[i]);
In parse_var_defs() if there is a problem allocating
var_defs.expr, the earlier var_defs.name is freed.
This free is duplicated by free_var_defs() which frees
the rest of the list.
Because free_var_defs() has to run anyway, remove the
second free fom parse_var_defs().
