KVM guest: fix bogus wallclock physical address calculation
(cherry picked from commit a20316d2aa41a8f4fd171648bad8f044f6060826)
The use of __pa() to calculate the address of a C-visible symbol
is wrong, and can lead to unpredictable results. See arch/x86/include/asm/page.h
for details.
It should be replaced with __pa_symbol(), that does the correct math here,
by taking relocations into account. This ensures the correct wallclock data
structure physical address is passed to the hypervisor.
