virtio-net: fix build error when CONFIG_AVERAGE is not enabled
Commit ab7db91705e9 ("virtio-net: auto-tune mergeable rx buffer size for
improved performance") introduced a virtio-net dependency on EWMA.
The inclusion of EWMA is controlled by CONFIG_AVERAGE. Fix build error
when CONFIG_AVERAGE is not enabled by adding select AVERAGE to
virtio-net's Kconfig entry.
Build failure reported using config make ARCH=s390 defconfig.
