This reverts commit 5500cdbe14d7435e04f66ff3cfb8ecd8b8e44ebf. We had numerous reports of premature ENOSPC that were bisected to this patch. Reverting will not break things but a warning in ''use_block_rsv'' may show up in the syslog. There''s no alternative fix in sight and the ENOSPC problem affects all 3.3 btrfs users during normal filesystem use.
