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")
