[Xen-devel] [PATCH 3/4] libxl/remus: Change the assert for info to an return



The assert(info) is after quite a lot of manipulations
on 'info' - which makes the assert pointless because if
info was NULL it would have crashed earlier.

Remove it and make it an return. Also since most of the
error paths are for the same rc, unify them.
