Do not hide errors when creating container with UserNSRoot

Browse Source 
This one is tricky. By using `:=` operator we have made err variable to be local
in the gorutine and different from `err` variable in the surrounding function.
And thus `createContainer` function returned always nil, even in cases when
some error occurred in the gorutine.
