Subject: [PATCH] xen/pciback: Fix incorrect type warnings

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
drivers/xen/xen-pciback/pci_stub.c:805:40: got int

drivers/xen/xen-pciback/pci_stub.c:862:40: expected restricted pci_channel_state_t [usertype] state
drivers/xen/xen-pciback/pci_stub.c:862:40: got int
drivers/xen/xen-pciback/pci_stub.c:973:31: warning: incorrect type in argument 2 (different base types)
drivers/xen/xen-pciback/pci_stub.c:973:31: expected restricted pci_channel_state_t [usertype] state
drivers/xen/xen-pciback/pci_stub.c:973:31: got int
