ixgbe: Merge ATR reinit into the service task

This change merges the ATR table reinitialization into the service task.
This is yet another opportunity to avoid any race conditions as we don't
want to be attempting to reinitialize the table during a possible reset.

In addition this change adds a counter for table reinitialization so that
it can be tracked as part of the regular statistics.
