[PATCH] nodemask.h: change any_online_node() to a static inline

[H Hartley Sweeten]

Change any_online_node() from a macro to a static inline function.
 
The macro any_online_node() uses the local symbol 'node', this causes a
sparse warning in net/sunrpc/svc.c.  Changing the macro to a static inline
function quites the sparse warning and will prevent the same warning
from possibly occurring in the future.
