Documentation: core-api: entry: Replace deprecated KVM entry/exit functions



The x86-specific functions kvm_guest_{enter,exit}_irqoff() were removed
and replaced by the generic guest_state_{enter,exit}_irqoff() in commit
ef9989af ("kvm: add guest_state_{enter,exit}_irqoff()") and commit
b2d2af7e ("kvm/x86: rework guest entry logic").

Update the references in the entry/exit handling documentation.
