Herbert Xu d701722aa3 crypto: api - Allow delayed algorithm destruction
The current algorithm unregistration mechanism originated from
software crypto.  The code relies on module reference counts to
stop in-use algorithms from being unregistered.  Therefore if
the unregistration function is reached, it is assumed that the
module reference count has hit zero and thus the algorithm reference
count should be exactly 1.

This is completely broken for hardware devices, which can be
unplugged at random.

Fix this by allowing algorithms to be destroyed later if a destroy
callback is provided.

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 reStructuredText 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.
