[ Upstream commit c0a50cd389c3ed54831e240023dd12bafa56b3a6 ]
When the driver hits an internal error condition returning DID_REQUEUE the I/O will be retried on the same ITL nexus. This will inhibit multipathing, resulting in endless retries even if the error could have been resolved by using a different ITL nexus. Return DID_TRANSPORT_DISRUPTED to allow for multipath to engage and route I/O to another ITL nexus.
