When device discovery is disabled during driver load time using module parameter
"disable_discovery=1" and when diag reset is issued then from logs, it is
observed
that the devices get added, removed and then added with new target ids.
So, inorder to limit this turn-off the code which is deleting and devices across
host reset when the disable_discovery module parameter is turned on.
