PCI: Delay after FLR of Solidigm P44 Pro NVMe

[ Upstream commit 0ac448e0 ]

Prevent KVM hang when a Solidgm P44 Pro NVMe is passed through to a guest
via IOMMU and the guest is subsequently rebooted.

A similar issue was identified and patched by 51ba0945 ("PCI: Delay
after FLR of Intel DC P3700 NVMe") and the same fix can be applied for this
case. (Intel spun off their NAND and SSD business as Solidigm and sold it
to SK Hynix in late 2021.)
