Subject: [PATCH] cdx: keep optional offload init failures non-fatal

The CDX module currently treats several board-specific acceleration paths as
mandatory. On boards without VWD/WiFi OH ports, fragmentation BMan pools, or
DPA IPsec OH ports, module init either fails or can crash before returning an
error.

Keep the CDX core loadable when those optional resources are absent:

  - warn and continue when VWD/WiFi init fails;
  - skip the vendor fragmentation module on this platform, because it can
    dereference a missing BMan pool;
  - warn and continue when DPA IPsec init fails;
  - only initialize DPA IPsec follow-up buffer pools when IPsec init succeeds.
