This patch sets up ZC for an Rx queue in a net device when an ifq is
registered with io_uring. The Rx queue is specified in the registration
struct.
For now since there is only one ifq, its destruction is implicit during
io_uring cleanup.

Let's get rid of this, since it isn't even typedef'ed on the networking
side. Doesn't really buy us anything, and it's only used once anyway.
That should naturally go away once we move from ndo_bpf
