Our users have reported a memory leak. The IPMI driver consumes a lot of
memory.

We found this problem because IPMI was slow to release messages after
being disconnected, causing what appeared to be a memory leak.

Fix commit as:
  ipmi: fix msg stack when IPMI is disconnected

Two other issues were solved in the process of solving this problem.

1. Unloading the driver takes a long time.

Fix commit as:
  ipmi: fix long wait in unload when IPMI disconnect

2. Memory leaks during driver unloading.

Fix commit as:
  ipmi: fix memleak when unload ipmi driver
