target: use unsigned int for timeout_ms

Change the prototype of functions:
- target_run_algorithm()
- target_wait_algorithm()
- target_wait_state()
- struct target_type::run_algorithm()
- struct target_type::wait_algorithm()
to use unsigned int for timeout_ms instead of int.
Change accordingly the variables passed as parameter.
