io_uring/zcrx: add user_struct and mm_struct to io_zcrx_ifq

Browse source

In preparation for removing ifq->ctx and making ifq lifetime independent
of ring ctx, add user_struct and mm_struct to io_zcrx_ifq.

In the ifq cleanup path, these are the only fields used from the main
ring ctx to do accounting. Taking a copy in the ifq allows ifq->ctx to
be removed later, including the ctx->refs held by the ifq.
