[PATCH 4/5] pi_stress: Fix error and debug message formatting

Fix three message formatting issues:

1. Incorrect barrier name in error message (line 212): The error
   referenced "all_threads_ready" but was actually checking
   "all_threads_done"

2. Typo in SCHED_DEADLINE error message (line 746): Fixed malformed
   parenthesis in "affinity*dl)" to "affinity (dl)"

3. Wrong format specifier (line 808): Variable 'count' is unsigned long
   but was using %d instead of %lu

These are cosmetic fixes that improve debugging clarity but don't
affect program behavior.
