Fix stdio_deregister_dev(...) device name comparison

[shmulikgo]

String comparison does not match 32 bytes length of dev->name.
Need to align temp_names to match stdio_dev.h:27 from 16 bytes to 32 bytes.

Please do not submit a Pull Request via github. Our project makes use of
mailing lists for patch submission and review. For more details please
see https://www.denx.de/wiki/U-Boot/Patches

The only exception to this is in order to trigger a CI loop on Azure prior
to posting of patches.

Like many other projects, U-Boot has a tradition of including big
blocks of License headers in all files. This not only blows up the
source code with mostly redundant information, but also makes it very
difficult to generate License Clearing Reports. An additional problem
is that even the same licenses are referred to by a number of
slightly varying text blocks (full, abbreviated, different
indentation, line wrapping and/or white space, with obsolete address
information, ...) which makes automatic processing a nightmare.

To make this easier, such license headers in the source files will be
replaced with a single line reference to Unique License Identifiers
as defined by the Linux Foundation's SPDX project [1]. For example,
in a source file the full "GPL v2.0 or later" header text will be
replaced by a single line:

    SPDX-License-Identifier:        GPL-2.0+

Ideally, the license terms of all files in the source tree should be
defined by such License Identifiers; in no case a file can contain
more than one such License Identifier list.

If a "SPDX-License-Identifier:" line references more than one Unique
License Identifier, then this means that the respective file can be
used under the terms of either of these licenses, i. e. with

    SPDX-License-Identifier:        GPL-2.0+        BSD-3-Clause

you can choose between GPL-2.0+ and BSD-3-Clause licensing.

We use the SPDX Unique License Identifiers here; these are available
at [2].
