Actually, netif_napi_del seems to be quite underused.  At least
approximately, I would assume that every file that uses netif_napi_add
should use netif_napi_del at least once, and possible more times.  But I
find 118 .c files that use netif_napi_add, and only 35 that use
netif_napi_del.

Are there some cases where it might not be needed?
