io_uring/zcrx: keep array of areas

Currently, we have only a one area per zcrx instance, and struct
io_zcrx_ifq stores a single pointer. To prepare for adding more areas,
replace it with an array of areas.

We'll be creating them at runtime, and the array is protected by 3
locks: ->pp_lock, ->alloc_lock and ->rq.lock. It takes all of them when
switching arrays, and readers should hold either of them.
