[XEN PATCH v2] common/sched: address a violation of MISRA C Rule 8.8

[<victorm.lira@xxxxxxx>]

From: Victor Lira <victorm.lira@xxxxxxx>

Rule 8.8: "The static storage class specifier shall be used in all
declarations of objects and functions that have internal linkage"

This patch fixes this by adding the static specifier.
No functional changes.
