This patch reworks and improves the pkey retry behavior for the pkey_ep11key2pkey() function. In contrast to the pkey_skey2pkey() function which is used to trigger a protected key derivation from an CCA secure data or cipher key the EP11 counterpart function had no proper retry loop implemented. This patch now introduces code which acts similar to the retry already done for CCA keys for this function used for EP11 keys.

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.
