i40evf: increase max number of queues

BugLink: http://bugs.launchpad.net/bugs/1536474
Future devices will allow for more queue pairs, so allocate a netdev
that can handle them. While we're at it, get rid of the separate
MAX_TX/MAX_RX defines. Since we always get matched queue pairs, having
these makes no sense.
