Aaron Ma e9669c2d05 ice: recap the VSI and QoS info after rebuild 
[ Upstream commit 6aa07e23dd ]

Fix IRDMA hardware initialization timeout (-110) after resume by
separating VSI-dependent configuration from RDMA resource allocation,
ensuring VSI is rebuilt before IRDMA accesses it.

After resume from suspend, IRDMA hardware initialization fails:
  ice: IRDMA hardware initialization FAILED init_state=4 status=-110

Separate RDMA initialization into two phases:
1. ice_init_rdma() - Allocate resources only (no VSI/QoS access, no plug)
2. ice_rdma_finalize_setup() - Assign VSI/QoS info and plug device

This allows:
- ice_init_rdma() to stay in ice_resume() (mirrors ice_deinit_rdma()
  in ice_suspend())
- VSI assignment deferred until after ice_vsi_rebuild() completes
- QoS info updated after ice_dcb_rebuild() completes
- Device plugged only when control queues, VSI, and DCB are all ready

Fixes: bc69ad7486 ("ice: avoid IRQ collision to fix init failure on ACPI S3 resume")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
