iscsi class: modify handling of replacement timeout
commit fdd46dcbe4468a1f47a2cc9be442d11c3d21dd68 upstream. This patch modifies the replacement/recovery_timeout so it works more like the fc fast io fail tmo. If userspace tries to set the replacement/recovery_timeout to less than zero, we will turn off the forced recovery cleanup. If userspace sets the value to 0 then we will force the recovery cleanup immediately.
