Every caller of __add_block_group_free_space() is checking if the flag BLOCK_GROUP_FLAG_NEEDS_FREE_SPACE is set before calling it. This is duplicate code and it's prone to some mistake in case we add more callers in the future. So move the check for that flag into the start of __add_block_group_free_space(), and, as a consequence, the path allocation from add_block_group_free_space() is moved into __add_block_group_free_space(), to preserve the behaviour of allocating a path only if the flag BLOCK_GROUP_FLAG_NEEDS_FREE_SPACE is set.

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.
