vhost_net: add missing lock nesting notation
[ Upstream commit aaa3149bbee9ba9b4e6f0bd6e3e7d191edeae942 ]
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: 0308813724606 ("vhost_net: basic polling support")
