xen/pciback: remove set but not used variable 'old_state'
[ Upstream commit 09e088a4903bd0dd911b4f1732b250130cdaffed ]
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/xen/xen-pciback/conf_space_capability.c: In function pm_ctrl_write:
drivers/xen/xen-pciback/conf_space_capability.c:119:25: warning:
variable old_state set but not used [-Wunused-but-set-variable]
It is never used so can be removed.
