kvmvapic: align start address as well as size
The kvmvapic code remaps a section of ROM as RAM to allow the guest to
maintain state there. It is careful to align the section size to a page
boundary, to avoid creating subpages, but neglects to do the same for
the start address. These leads to an assert later on when the memory
core tries to create a page which is half RAM and half ROM.
Fix by aligning the start address to a page boundary.
This can be triggered by running qemu-system-x86_64 -enable-kvm -vga none.
