When we look for checksum items, through csum_exist_in_range(), at can_nocow_extent(), we no longer need the path that we have previously allocated. Through csum_exist_in_range() -> btrfs_lookup_csums_range(), we also end up allocating a path, so we are adding unnecessary extra memory usage. So free the path before calling csum_exist_in_range().

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.
