stacktrace: cleanup inconsistent variable type
Modify the variable type of 'skip' member of struct stack_trace. In theory, the 'skip' variable type should be unsigned int. There are two reasons: - The 'skip' only has two situation, 1)Positive value, 2)Zero - The 'skip' of struct stack_trace has inconsistent type with struct stack_trace_data, it makes a bit confusion in the relationship between struct stack_trace and stack_trace_data.
