[PATCH next] btrfs: tests: Fix double free in remove_extent_ref()

[Dan Carpenter <dan.carpenter@linaro.org>]

We converted this code to use auto free cleanup.h magic but one old
school free was accidentally left behind which leads to a double free
bug.

Fixes: a320476ca8a3 ("btrfs: tests: do trivial BTRFS_PATH_AUTO_FREE conversions")
