[PATCH 2/3] vfio/pci: Fix unchecked return value

From: Alex Williamson
Date: Mon Apr 07 2014 - 18:29:53 EST


There's nothing we can do different if pci_load_and_free_saved_state()
fails, other than maybe print some log message, but the actual re-load
of the state is an unnecessary step here since we've only just saved
it. We can cleanup a coverity warning and eliminate the unnecessary
stop by freeing the state ourselves.

Detected by Coverity: CID 753101
