Revert "PCI: Clear PCI_STATUS when setting up device"

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_virtual_machine?language=objc)

6cd514e58f12 only solved a cosmetic problem, so revert it to fix the boot
failures.
