ice: Always set prefena when configuring an Rx queue

Browse source

Currently we are always setting prefena to 0. This is causing the
hardware to only fetch descriptors when there are none free in the cache
for a received packet instead of prefetching when it has used the last
descriptor regardless of incoming packets. Fix this by allowing the
hardware to prefetch Rx descriptors.
