ixl(4): Fix potential driver interrupt setup issues and startup crash.
- Limit queue autoconfiguration to 8 queues to prevent the driver from
requesting a large number of MSI-X vectors at boot.
- Fix potential kernel panic that occurs when the driver loads and cannot
get all requested MSIX vectors. Instead, attach() will fail with an error.
- Move taskqueue setup to later in attach() to prevent having to free
taskqueues if some other error in attach() occurs.
