fsdev: improve error handling of backend init
This patch changes some error messages in the backend init code and convert backends to propagate QEMU Error objects instead of calling error_report(). One notable improvement is that the local backend now provides a more detailed error report when it fails to open the shared directory. Signed-off-by: Greg Kurz <groug@kaod.org>
