[RFC PATCH 3/3] replace xfs_iflush_all with xfs_reclaim_all

[Christoph Hellwig <hch@lst.de>]

xfs_iflush_all is another variant of the loop all deleted inodes
without vnode and flush them scheme.  Use xfs_finish_reclaim_all
without the nonblock flag and with XFS_IFLUSH_ASYNC as sync_flag
instead.

Btw, shouldn't xfs_quiesce_fs also pass XFS_IFLUSH_ASYNC to
xfs_finish_reclaim_all?
