If rport target discovery commands fail for some reason, they get retried
up to a set number of retries. Once the retry limit is exceeded, the
target is deleted. In order to delete the target, we either need to
do an implicit logout or a move login. In the move login case, if the
move login fails, we want to retry it. This ensures the retry counter
gets reinitialized so the move login will get retried.
