lockdep_assert_held() is better suited to checking locking requirements, since it won't get confused when someone else holds the lock. This is also a step towards possibly removing spin_is_locked().

2016-04-11snic: Fixing race in the hba reset and IO/TM completionNarsimhulu Musini
While HBA reset is in progress, if IO/TM completion is received for the same IO then IO/TM completion path releases the driver private resources associated with IO. This fix prevents releasing the resources in IO and TM completion path if HBA reset is in progress.
