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.
