[PATCH 6.6] btrfs: free path if inline extents in range_is_hole_in_parent()

[Hongbo Li <lihongbo22@huawei.com>]

Commit f2dc6ab3a14c ("btrfs: send: check for inline extents in
range_is_hole_in_parent()") is a patch backported directly from
mainline to 6.6, it does not free the path in the inline extents case.

Commit 4ca6f24a52c4 ("btrfs: more trivial BTRFS_PATH_AUTO_FREE
conversions") in 6.18-rc1 fixes this by accident by converting to
BTRFS_PATH_AUTO_FREE, but we cannot backport this to 6.6 due to many
dependencies. Instead, we choose to use a goto statement to avoid the
memory leak in inline extents case.
