Reset the command register when assigning a PCI device to a guest:
according to the PCI spec the PCI_COMMAND register is typically all 0's
after reset, but this might not be true for the guest as it needs
to respect host's settings.
For that reason, do not write 0 to the PCI_COMMAND register directly,
but go through the corresponding emulation layer (cmd_write), which
will take care about the actual bits written.

Since v6:
- use cmd_write directly without introducing emulate_cmd_reg
- update commit message with more description on all 0's in PCI_COMMAND
I agree with the change,
thanks, may I please ask can this be converted to some tag?
I could offer a R-b, but you've got one from Rahul already, so mine
won't buy you anything further. What you will need is a maintainer
ack, which imo isn't a priority since this is only patch 8 in a
series which itself depends on a further series likely continuing
to be controversial (didn't get there yet).
ok, fair enough.
