pc: kvm: check if KVM has free memory slots to avoid abort()
When more memory devices are used than available
KVM memory slots, QEMU crashes with:
kvm_alloc_slot: no free slot available
Aborted (core dumped)
Fix this by checking that KVM has a free slot before
attempting to map memory in guest address space.
