  Revert "nvme-pci: clamp max_hw_sectors based on DMA optimized limitation" (2026-10-15 07:20:49 -0700)

----------------------------------------------------------------
nvme updates for Linux 7.4

 - Parallelize nvme-tcp I/O queue setup and use the caller's network
   namespace
 - New multipath sysfs attributes for path state, available
   iopolicies, and fail on controller loss
 - Multipath fixes for failfast/ANA path evaluation and discovery
   subsystem iopolicy reporting
 - Apple M4 ANS2 NVMe support
 - Traffic based keep alive support for the target
 - DH-HMAC-CHAP hardening for host and target: enforce bidirectional
   auth, require auth before property set, fix state UAF, reject short
   payloads, restrict secret visibility
 - Target reservation preempt fixes
 - Target passthru I/O use-after-free fix
 - Fix out-of-bounds reads and memory leaks from device and host
   supplied data: FDP config log, ZNS zone reports, file namespace
   range errors
 - Enforce partition checks for unprivileged passthrough
 - nvme-rdma fix for bogus remote invalidation
 - nvmet-fc fix for recursive locking hang on port unlink
 - Revert DMA opt max_hw_sectors clamp due to performance regressions
 - Misc cleanups
