ice: Don't allow more channels than LAN MSI-X available
Currently users could create more channels than LAN MSI-X available.
This is happening because there is no check against pf->num_lan_msix
when checking the max allowed channels and will cause performance issues
if multiple Tx and Rx queues are tied to a single MSI-X. Fix this by not
allowing more channels than LAN MSI-X available in pf->num_lan_msix.
