When using nanosleep() in an userspace application we get a
ratelimit warning
NOHZ: local_softirq_pending 08
for 10 times.
This patch replaces netif_rx() with netif_rx_ni() which has
to be used from process/softirq context.
The process/softirq context will be called from fakelb driver.
See linux-kernel commit 481a819 for similar fix.
