Avi Kivity 961e80ab74 Be more conservative when deciding when to shut down due to disk errors
Currently we only shut down on EIO.  Expand this to shut down on any
system_error.

This may cause us to shut down prematurely due to a transient error,
but this is better than not shutting down due to a permanent error
(such as ENOSPC or EPERM).  We may whitelist certain errors in the future
to improve the behavior.

Fixes #1311.
