net/mlx5e: Add stale counter for PCIe congestion events

2025-09-10T02:21:30+00:00

This ethtool counter is meant to help with observing how many times the congestion event was triggered but on query there was no state change. This would help to indicate when a work item was scheduled to run too late and in the meantime the congestion state changed back to previous state. While at it, do a driveby typo fix in documentation for pci_bw_inbound_high.
