For Texas' SSD the login req is rejected

For Mellanox srp target the new multi channel/connection is 
established; however, if the host is in error recovery and 
do target reset, the host should terminate all outstanding

dangled on multi-channel/connection and try to complete the 
I/Os. This is violate scsi task management
