[PATCH] pci-arbiter: Remove invalid pci_device_close

[Damien Zammit]

pci_control_port is not a port info
so calling deref on it is invalid.
There seems no reason to have a device_close
for the pci device currently so remove it.

Perhaps some logic needs to be added to prevent
concurrent pci accesses by multiple clients
since some pci commands are non-atomic (?)
