Filipe Manana f5190da518 btrfs: fix leaf leak in an error path in btrfs_del_items() ...

[ Upstream commit e7dd1182fc ]

If the call to btrfs_del_leaf() fails we return without decrementing the
extra ref we took on the leaf, therefore leaking it. Fix this by ensuring
we drop the ref count before returning the error.

Fixes: 751a27615d ("btrfs: do not BUG_ON() on tree mod log failures at btrfs_del_ptr()")
