intf->cmd_rcvrs is traversed with list_for_each_entry_rcu outside an RCU read-side critical section but under the protection of intf->cmd_rcvrs_mutex. ipmi_interfaces is traversed using list_for_each_entry_rcu outside an RCU read-side critical section but under the protection of ipmi_interfaces_mutex. Hence, add the corresponding lockdep expression to the list traversal primitive to silence false-positive lockdep warnings, and harden RCU lists. Add macro for the corresponding lockdep expression to make the code clean and concise.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
