Subject: [PATCH] RHEL: Fix maxvcpus output

https://bugzilla.redhat.com/show_bug.cgi?id=1092363

RHEL-only.

Ignore the maximum vcpu limit (KVM_CAP_MAX_VCPUS) on RHEL,

since RHEL QEMU treats the recommended limit (KVM_CAP_NR_VCPUS)

as the maximum, see:

https://bugzilla.redhat.com/show_bug.cgi?id=998708
