Jason Wang 1cb81756b7 vhost_net: add missing lock nesting notation 
[ Upstream commit aaa3149bbe ]

We try to hold TX virtqueue mutex in vhost_net_rx_peek_head_len()
after RX virtqueue mutex is held in handle_rx(). This requires an
appropriate lock nesting notation to calm down deadlock detector.

Fixes: 0308813724 ("vhost_net: basic polling support")
