Subject: 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.
