scsi: storvsc: properly handle SRB_ERROR when sense message is present



commit bba5dc332ec2d3a685cb4dae668c793f6a3713a3 upstream.

When sense message is present on error, we should pass along to the upper
layer to decide how to deal with the error.
This patch fixes connectivity issues with Fiber Channel devices.
