kvm_set_phys_mem can be called to reallocate a slot by something the guest does (e.g. writing to PAM and other chipset registers). This can happen in the middle of a migration, and if we're unlucky it can now happen between the split 'sync' and 'clear'; the clear asserts if there's no bmap to clear. Recreate the bmap whenever we change the slot, keeping the clear path happy. Typically this is triggered by the guest rebooting during a migrate.
