ipmi: Use dev_warn_ratelimited() for incorrect message warnings

During BMC firmware upgrades on live systems, the ipmi_msghandler
generates excessive "BMC returned incorrect response" warnings
while the BMC is temporarily offline. This can flood system logs
in large deployments.

Replace dev_warn() with dev_warn_ratelimited() to throttle these
warnings and prevent log spam during BMC maintenance operations.

"Restructure the IPMI driver.

This is a restructure of the IPMI driver, mostly to remove SRCU. The
locking had issues, and they were not going to be straightforward to
fix. Plus it used tons of memory and was generally a pain.

Most of this moves handling of messages out of bh and interrupt
context and runs it in thread context. Then getting rid of SRCU is
easy.

This also has a minor cleanup to remove a warning on newer GCCs and to
fix some documentation"

ipmi:msghandler: Fix potential memory corruption in ipmi_create_user()

The "intf" list iterator is an invalid pointer if the correct
"intf->intf_num" is not found. Calling atomic_dec(&intf->nr_users) on
and invalid pointer will lead to memory corruption.

We don't really need to call atomic_dec() if we haven't called
atomic_add_return() so update the if (intf->in_shutdown) path as well.

then the interface to be freed.

ipmi:msghandler: Fix locking around users and interfaces

Now that SRCU is gone from IPMI, it can no longer be sloppy about
locking. Use the users mutex now when sending a message, not the big
ipmi_interfaces mutex, because it can result in a recursive lock. The
users mutex will work because the interface destroy code claims it after
setting the interface in shutdown mode.

Also, due to the same changes, rework the refcounting on users and
interfaces. Remove the refcount to an interface when the user is
freed, not when it is destroyed. If the interface is destroyed
while the user still exists, the user will still point to the
interface to test that it is valid if the user tries to do anything
but delete the user.
