[ Upstream commit 44e985938e85503d0a69ec538e15fd33c1a4df05 ]
This reverts commit 6cd514e58f12b211d638dbf6f791fa18d854f09c.
Christophe Fergeau reported that 6cd514e58f12 ("PCI: Clear PCI_STATUS when setting up device") causes boot failures when trying to start linux guests with Apple's virtualization framework (for example using https://developer.apple.com/documentation/virtualization/running_linux_in_a_...)
6cd514e58f12 only solved a cosmetic problem, so revert it to fix the boot failures.
