ixgbe: Compare flow control against requested mode
The flow-control sysctl represents the configured policy, while
current_mode is the mode negotiated with the link partner. Comparing a
new request with current_mode can needlessly reprogram an unchanged
policy or skip a requested policy change that happens to match the
current negotiation result.
Compare with requested_mode before deciding that no update is needed.
