CVE-2025-71268

In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix reservation leak in some error paths when inserting inline extent

If we fail to allocate a path or join a transaction, we return from
__cow_file_range_inline() without freeing the reserved qgroup data,
resulting in a leak. Fix this by ensuring we call btrfs_qgroup_free_data()
in such cases.
