If we can't read a reliable write pointer from a sequential zone fail creating the block group with an I/O error. Also if the read write pointer is beyond the end of the respective zone, fail the creation of the block group on this zone with an I/O error. While this could also happen in real world scenarios with misbehaving drives, this issue addresses a problem uncovered by fstests' test case generic/475.

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.
