While initializing an SDIO card in mmc_sdio_init_card(), we may need to retry the UHS-I specific initialization, in case the first attempt fails. This leads to resending a CMD8, but also to restart from scratch with the so called OCR mask negotiations. This is unnecessary as we already have a negotiated OCR mask, so let's use that instead. In this way, the behaviour also becomes more consistent with other similar paths.

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.
