xics/kvm: Always use local_err in xics_kvm_init() 

Passing both errp and &local_err to functions is a recipe for messing
things up.

Since we must use &local_err for icp_kvm_realize(), use &local_err
everywhere where rollback must happen and have a single call to
error_propagate() them all. While here, add errno to the error
message.
