Leon Romanovsky 3a4ef2e2b5 RDMA/rdmavt: Catch use-after-free access of AH structures 
Prior to commit d345691471 ("RDMA: Handle AH allocations by IB/core"),
AH destroy path is rdmavt returned -EBUSY warning to application and
caused to potential leakage of kernel memory of AH structure.

After that commit, the AH structure is always freed but such early return
in driver code can potentially cause to use-after-free error.

Add warning to catch such situation to help driver developers to fix AH
release path.

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.
