KVM/nVMX: Do not validate that posted_intr_desc_addr is page aligned
The spec only requires the posted interrupt descriptor address to be
64-bytes aligned (i.e. bits[0:5] == 0). Using page_address_valid also
forces the address to be page aligned.
Only validate that the address does not cross the maximum physical address
without enforcing a page alignment.
