Subject: btrfs: Free correct amount of space in
 btrfs_delayed_inode_reserve_metadata
Patch-mainline: Submitted, 23.02.2020 - btrfs mailing list
References: bsc#1182047

Following commit f218ea6c4792 ("btrfs: delayed-inode: Remove wrong
qgroup meta reservation calls") this function now reserves num_bytes,
rather than the fixed amount of nodesize. As such this requires the
same amount to be freed in case of failure. Fix this by adjusting
the amount we are freeing.

Fixes f218ea6c4792 ("btrfs: delayed-inode: Remove wrong qgroup meta reservation calls")
