ipmi: Add a sysfs count of total outstanding messages for an interface

Go through each user and add its message count to a total and print the

It would be nice to have a per-user file, but there's no user sysfs
entity at this point to hang it off of. Probably not worth the effort.

ipmi:ipmi_ipmb: Fix null-ptr-deref in ipmi_unregister_smi()

In ipmi_ipmb_probe(), 'iidev->intf' is not set before
ipmi_register_smi() success. And in the error handling case,
ipmi_ipmb_remove() is called to release resources, ipmi_unregister_smi()
is called without check 'iidev->intf', this will cause KASAN
null-ptr-deref issue.

General kernel style is to allow NULL to be passed into unregister
calls, so fix it that way. This allows a NULL check to be removed in
other code.

ipmi: When handling send message responses, don't process the message

A chunk was dropped when the code handling send messages was rewritten.
Those messages shouldn't be processed normally, they are just an
indication that the message was successfully sent and the timers should
be started for the real response that should be coming later.

Add back in the missing chunk to just discard the message and go on.
