MIPS: KVM: Use virt_to_phys() to get commpage PFN

Browse source

Calculate the PFN of the commpage using virt_to_phys() instead of
CPHYSADDR(). This is more portable as kzalloc() may allocate from XKPhys
instead of KSeg0 on 64-bit kernels, which CPHYSADDR() doesn't handle.
This is sufficient for highmem kernels too since kzalloc() will allocate
from lowmem in KSeg0.
