This patch fix the following sparse warning by applying
__force cast to pci_ers_result_t and pci_power_t.
drivers/xen/xen-pciback/pci_stub.c:760:16: sparse: warning: cast to restricted pci_ers_result_t
drivers/xen/xen-pciback/conf_space_capability.c:125:22: sparse: warning: cast to restricted pci_power_t
No functional changes intended.
