Yep thanks. In short, read the code better Michael :)
I folded in this hunk, which will keep the compiler happy and is also
correct I believe. Basically in the success case (lmbs_added == lmbs_to_add)
we explicitly set rc to 0.

Check if an LMB is assigned before attempting to call dlpar_acquire_drc in
order to avoid any unnecessary rtas calls. This substantially reduces the
running time of memory hot add on lpars with large amounts of memory.
