[PATCH] xen/pciback: Fix incorrect type warnings

[Muhammad Usama Anjum <musamaanjum@xxxxxxxxx>]

Correct enum pci_channel_io_normal should be used instead of putting
integer value 1.

Fix following smatch warnings:
drivers/xen/xen-pciback/pci_stub.c:805:40: warning: incorrect type in argument 
2 (different base types)
drivers/xen/xen-pciback/pci_stub.c:805:40:    expected restricted 
pci_channel_state_t [usertype] state
