0b252a7000 Revert "nvmf: only poll admin queue once every 10 ms"
This is causing issues during shutdown because the poller removal is not
synchronized with the rest of the cleanup path.

This reverts commit 7dfc5e922d.

7dfc5e922d nvmf: only poll admin queue once every 10 ms
This should enhance performance, since the hardware admin queue poll
function takes a mutex and should not be in the performance path.

5d8c94536a event: hide struct spdk_poller internals
This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).

It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.

052be2f540 nvmf: Each listen addr gets its own PORT ID
PORT IDs indicate hardware failure domains according
to the NVMf specification, which means they should
indicate which transport addresses are on the same
NIC. Unfortunately, that doesn't really make sense for
IP-based fabrics because IP addresses can move. The
safest way to present this is to show all IP addresses
as part of different subsystem ports.

These can be simplified and merged into the subsystem.

Remove the concept of mappings from subsystems and replace
it with a list of hosts and ports. The host is optional -
not specifying a host means any host can connect.
