Since each pf does not share the same structure space, the first
mask value should start at 0 instead of hw->pf_id * per_pf to avoid
address overflow. Otherwise, address space will overlap when
masks.first + masks.count > ICE_PROF_MASK_COUNT, and it may lead to
unexpected variable assignment, which causes segmentation fault.

vectors")
