x86/xen: Fix incorrect per_cpu accessor in xen_clocksource_read()
Commit 89cbc76768c2 ("x86: Replace __get_cpu_var uses") replaced
__get_cpu_var() with this_cpu_ptr() in xen_clocksource_read() in such a
way that instead of accessing a structure pointed to by a per-cpu pointer
we are trying to get to a per-cpu structure.
__this_cpu_read() of the pointer is the more appropriate accessor.
