Why "user" then? :-)

Well, after some digging in brains I find that I use home-made terminology.
non-interrupt/non-bh context is called "process context" here. :-)
"Normal context" is process context with enabled BHs and irqs.

I experience even more unpleasant feelings, when thinking what would happen
if netif_rx() without these __ is called from under irq protected spinlock.

I caught you! :-) Each "context" is normal, but "environment" still can
be wrong.

Yes, I agreed. It is the simplest solution. In any case, all the instances
of netif_rx are to be checked for spinlock-safeness.
