ppc/kvm: Replace ACCESS_ONCE with READ_ONCE
commit 5ee07612e9e20817bb99256ab6cf1400fd5aa270 upstream.
ACCESS_ONCE does not work reliably on non-scalar types. For
example gcc 4.6 and 4.7 might remove the volatile tag for such
accesses during the SRA (scalar replacement of aggregates) step
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58145)
Change the ppc/kvm code to replace ACCESS_ONCE with READ_ONCE.
