[PATCH] stacktrace: cleanup inconsistent variable type

[Walter Wu]

The skip in 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. In theory,
the skip variable type should be unsigned int.
