[PATCH v2 1/2] xen/page_alloc: address violation of Rule 14.3

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

From: Federico Serafini <federico.serafini@xxxxxxxxxxx>

MISRA C Rule 14.3 states that "Controlling expressions shall not be
invariant".

Change the #define to static inline to resolve the violation.
