[PATCH v2 1/6] xen: Always calculate max_cpus value

[Daniel Kiper]

max_cpus is not available since 20374 changeset (Miscellaneous data
placement adjustments). It was moved to __initdata section. This section
is freed after Xen initialization. Assume that max_cpus is always
equal to XEN_HYPER_SIZE(cpumask_t) * 8.
