Documentation: kvm: fix messy conversion from .txt to .rst

Building the documentation gives a warning that the KVM_PPC_RESIZE_HPT_PREPARE
label is defined twice.  The root cause is that the KVM_PPC_RESIZE_HPT_PREPARE
API is present twice, the second being a mix of the prepare and commit APIs.
Fix it.

 Used to implement the PAPR extension for runtime resizing of a guest's
 Hashed Page Table (HPT).  Specifically this starts, stops or monitors
 the preparation of a new potential HPT for the guest, essentially
