Various null pointer dereference and general protection fault panics
occur when there is a link bounce under load. There are a large number

The issues resolve to list corruptions due to missing or inconsistent
lock protection. Lockups are due to nested locks in the unsolicited
abort path. The unsolicited abort path calls the wrong abort
processing routine. There was also duplicate context release while
aborts were still active in the hardware.
Removed duplicate locks and added lock protection around list item
removal. Commonized lock handling around the abort processing routines.
Prevent context release while still in ABTS list.
