Revert "PCI: Clear PCI_STATUS when setting up device" 

This reverts commit 6cd514e5.

Christophe Fergeau reported that 6cd514e5 ("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)

6cd514e5 only solved a cosmetic problem, so revert it to fix the boot
failures.
