[SCSI] ibmvfc: Fix error reporting for some FC errors
If either a "transport fault" or a "general transport" error is received and no other error information is available, the command is improperly returned as successful. Fix this to return DID_ERROR in this case. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
