Commit 14ec35ff5786 ("entry: Rename "kvm" entry code assets to "virt" to
genericize APIs") renames the config KVM_XFER_TO_GUEST_WORK to
VIRT_XFER_TO_GUEST_WORK. In a concurrent development work with commit
f51fe3b7e48c ("Documentation: Add real-time to core-api"), the
documentation on making an architecture support PREEMPT_RT has been
included referring to this config with its previous name.
Adjust the documentation to the current situation, and specifically
refer to the new name of the config.
Fixes: f51fe3b7e48c ("Documentation: Add real-time to core-api")
