Instead of using an if-else statement when processing the extent item at btrfs_lookup_extent_info(), use a single if statement for the error case since it does a goto at the end and leave the success (expected) case following the if statement, reducing indentation and making the logic a bit easier to follow. Also make the if statement's condition as unlikely since it's not expected to ever happen, as it signals some corruption, making it clear and hint the compiler to generate more efficient code.

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 reStructuredText 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.
