xfs: update for 3.9-rc1 

For 3.9-rc1 there are primarily bugfixes and a few cleanups.
 
 - fix(es) for compound buffers
 - remove unused XFS_TRANS_DEBUG routines
 - fix for dquot soft timer asserts due to overflow of d_blk_softlimit
 - don't zero allocation args structure members after they are memset(0)
 - fix for regression in dir v2 code introduced in commit 20f7e9f3
 - remove obsolete simple_strto<foo>
 - fix return value when filesystem probe finds no XFS magic, a
   regression introduced in 9802182.
 - remove boolean_t typedef completely
 - fix stack switch in __xfs_bmapi_allocate by moving the check for stack
   switch up into xfs_bmapi_write.
 - fix build error due to incomplete boolean_t removal
 - fix oops in _xfs_buf_find by validating that the requested block is
   within the filesystem bounds.
 - limit speculative preallocation near ENOSPC.
 - fix an unmount hang in xfs_wait_buftarg by freeing the
   xfs_buf_log_item in xfs_buf_item_unlock.
 - fix a possible use after free with AIO.
 - fix xfs_swap_extents after removal of xfs_flushinval_pages, a
   regression introduced in fb59581404.
 - replace hardcoded 128 with log header size
 - add memory barrier before wake_up_bit in xfs_ifunlock
 - limit speculative preallocation on sparse files
 - fix xa_lock recursion bug introduced in 90810b9e82
 - fix write verifier for symlinks
