[ Upstream commit cd9aed606088d36a7ffff3e808db4e76b1854285 ] nvme_configure_metadata() is issuing I/O, so we might incur an I/O error which will cause the connection to be reset. But in that case any further probing will race with reset and cause UAF errors. So return a status from nvme_configure_metadata() and abort probing if there was an I/O error.

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.
