nvme updates for Linux 6.16

 - add per-node DMA pools and use them for PRP/SGL allocations
   (Caleb Sander Mateos, Keith Busch)
 - nvme-fcloop refcounting fixes (Daniel Wagner)
 - support delayed removal of the multipath node and optionally support
   the multipath node for private namespaces (Nilay Shroff)
 - support shared CQs in the PCI endpoint target code (Wilfred Mallawa)
 - support admin-queue only authentication (Hannes Reinecke)
 - use the crc32c library instead of the crypto API (Eric Biggers)
 - misc cleanups (Christoph Hellwig, Marcelo Moreira, Hannes Reinecke,
   Leon Romanovsky, Gustavo A. R. Silva)
