The x86-specific functions kvm_guest_{enter,exit}_irqoff() were removed
and replaced by the generic guest_state_{enter,exit}_irqoff() in commit
ef9989afda73 ("kvm: add guest_state_{enter,exit}_irqoff()") and commit
b2d2af7e5df3 ("kvm/x86: rework guest entry logic").
Update the references in the entry/exit handling documentation.

The topic of nesting and reentrancy in the context of early entry code
hasn't been addressed so far. So do it.
