  PCI: Don't treat ~0 as ready in pci_dev_wait() with RRS SV (2026-10-16 12:11:15 -0500)

Updated this morning to add Samsung 990 EVO Plus to the Immediate Readiness
quirk.

----------------------------------------------------------------

  - Ignore Immediate Readiness on Samsung 990 PRO and 990 EVO Plus NVMe,
    which falsely advertise it; removal of unrelated delays in v7.2 caused
    post-FLR state restoration to fail, resulting in a VFIO passthrough
    regression (Alexander Gruhlke)

  - Don't treat ~0 as 'device is ready' in pci_dev_wait(); with RRS SV, a
    device may respond with RRS (resulting in data of 0x0001) or may not
    respond at all (typically resulting in ~0 data).  A v6.12 change
    treated ~0 as 'ready', resulting in a regression with Intel and Samsung
    NVMe SSDs (Alexander Gruhlke)
