[Xen-devel] [PATCH 2/3] libxl/remus: Move the assert before the info is used.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

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.

Move it earlier so that it guards before we try using
the 'info' structure.
