KVM: Drop KVM_REQ_MMU_RELOAD and update vcpu-requests.rst documentation
Remove the now unused KVM_REQ_MMU_RELOAD, shift KVM_REQ_VM_DEAD into the unoccupied space, and update vcpu-requests.rst, which was missing an entry for KVM_REQ_VM_DEAD. Switching KVM_REQ_VM_DEAD to entry '1' also fixes the stale comment about bits 4-7 being reserved.

- When shadow page tables are used and memory slots are removed it's
- necessary to inform each VCPU to completely refresh the tables. This
- request is used for that.
+ This request informs all VCPUs that the VM is dead and unusable, e.g. due to
+ fatal error or because the VM's state has been intentionally destroyed.
