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.

KVM_REQ_MMU_RELOAD

KVM_REQ_VM_DEAD



  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.
