[PATCH 2/4] Documentation: kvm: update KVM_GET_EMULATED_CPUID ioctl description

[Emanuele Giuseppe Esposito]

KVM_GET_EMULATED_CPUID returns -E2BIG if the nent field of
struct kvm_cpuid2 is smaller than the actual entries, while
it adjusts nent if the provided amount is bigger than the
actual amount.

Update documentation accordingly. ENOMEM is just returned if the
allocation fails, like all other calls.
