recieve: disable NAPI busy polling

This avoids adding one reference per peer to the napi_hash hashtable, as
normally done by netif_napi_add(). Since we potentially could have up to
2^20 peers this would make busy polling very slow globally.

This approach is preferable to having only a single napi struct because
we get one gro_list per peer, which means packets can be combined nicely
even if we have a large number of peers.

This is also done by gro_cells_init() in net/core/gro_cells.c .
