Description

In the Linux kernel, the following vulnerability has been resolved:

rust_binder: cancel deferred work items in thread exit

If there are deferred work items on the thread todo list, then they are
not cleaned up in the Thread::release() method. Thus, update the code to
clean up the work items even if they are deferred.

This can happen if the thread dies while it has an active outgoing
transaction.
