Handle guest access failures

When testing SMB filesystem access with XenServer we discovered that if guest access is attempted to a Windows share that requires authentication the connection establishment stage in the kernel went into a non-recoverable (without kill -9 of the mount command) loop attempting to follow a DFS referal. The cause of this is that the error now surfaces later in the process than previously and all errors were considered to be the same and caused a DFS referal step.
