Pull more xfs updates from Dave Chinner:
 "This update is largely bug fixes and cleanups for all the code merged
  in the first pull request. The majority of them are to the new logged
  attribute code, but there are also a couple of fixes for other log
  recovery and memory leaks that have recently been found.

  Summary:

   - fix refcount leak in xfs_ifree()

   - fix xfs_buf_cancel structure leaks in log recovery

   - fix dquot leak after failed quota check

   - fix a couple of problematic ASSERTS

   - fix small aim7 perf regression in from new btree sibling validation

   - clean up log incompat feature marking for new logged attribute
     feature

   - disallow logged attributes on legacy V4 filesystem formats.

   - fix da state leak when freeing attr intents

   - improve validation of the attr log items in recovery

   - use slab caches for commonly used attr structures

   - fix leaks of attr name/value buffer and reduce copying overhead
     during intent logging

   - remove some dead debug code from log recovery"
