[DLM] fix user unlocking
When a user process exits, we clear all the locks it holds. There is a
problem, though, with locks that the process had begun unlocking before it
exited. We couldn't find the lkb's that were in the process of being
unlocked remotely, to flag that they are DEAD. To solve this, we move
lkb's being unlocked onto a new list in the per-process structure that
tracks what locks the process is holding. We can then go through this
list to flag the necessary lkb's when clearing locks for a process when it
exits.
