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

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

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

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

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