qga: Rename guest-get-devices return member 'address' to 'id'

Member 'address' is union GuestDeviceAddress with a single branch
GuestDeviceAddressPCI, containing PCI vendor ID and device ID.  This
is not a PCI address.  Type GuestPCIAddress is.  Messed up in recent
commit 2e4211cee4 "qga: add command guest-get-devices for reporting
VirtIO devices".

Rename type GuestDeviceAddressPCI to GuestDeviceIdPCI, type
GuestDeviceAddress to GuestDeviceId, and member 'address' to 'id'.

Document the member properly while there.
