alx: take rtnl before calling __alx_open from resume
The __alx_open function can be called from ndo_open, which is called under RTNL, or from alx_resume, which isn't. Since commit d768319cd427, we're calling the netif_set_real_num_{tx,rx}_queues functions, which need to be called under RTNL. This is similar to commit 0c2cc02e571a ("igb: Move the calls to set the Tx and Rx queues into igb_open"). Fixes: d768319cd427 ("alx: enable multiple tx queues") Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S. Miller <davem@davemloft.net>
