btrfs: warn when extent buffer leak test fails
Although we have btrfs_extent_buffer_leak_debug_check() (enabled by CONFIG_BTRFS_DEBUG option) to detect and warn QA testers that we have some extent buffer leakage, it's just pr_err(), not noisy enough for fstests to cache. So here we trigger a WARN_ON() if the allocated_ebs list is not empty.
