[v2,3/2] xfs: fix simple problems with log intent recovery

Commit Message

From: Darrick J. Wong <[e-mail]>

Nowadays, log recovery will call ->release on the recovered intent items
if recovery fails.  Therefore, it's redundant to release them from
inside the ->recover functions when they're about to return an error.

v2: log recovery already cancels the intents for us, so don't free them
