Eric Dumazet 5c553262f0 net: netdevsim: fix nsim_pp_hold_write() 
[ Upstream commit b9b8301d36 ]

nsim_pp_hold_write() has two problems:

1) It may return with rtnl held, as found by syzbot.

2) Its return value does not propagate an error if any.

Fixes: 1580cbcbfe ("net: netdevsim: add some fake page pool use")
