For read_one_block_group(), its only caller has already got the item key to search next block group item. So we can use that key directly without doing our own convertion on stack. Also, since that key used in btrfs_read_block_groups() is vital for block group item search, add 'const' keyword for that parameter to prevent read_one_block_group() to modify it.

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.
