intel/perf: delete dead code.
What does this MR do and why?
intel/perf: delete dead code.
The inner loop with p is dead, because n_passes_written is no longer
updated as of 56bd81ee21cb42e4a5afa2939514b570a1283754, so it is always
comparing a uint32_t < 0, which is never true. Since the inner loop is
dead code, the pass array is dead code, as it simply keeps writing to
element 0, and but never reads or uses it, along with all of the pass
count information.
