When multiple async FDs were allowed to exist the idea was for all
broadcast events to be delivered to all async FDs, however
IB_EVENT_DEVICE_FATAL was missed.
Instead of having ib_uverbs_free_hw_resources() special case the global
async_fd, have it cause the event during the uobject destruction. Every
async fd is now a uobject so simply generate the IB_EVENT_DEVICE_FATAL
while destroying the async fd uobject. This ensures every async FD gets a
copy of the event.
Fixes: d680e88e20 ("RDMA/core: Add UVERBS_METHOD_ASYNC_EVENT_ALLOC")

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.
