Btrfs: fix lockdep warning
The locking order for stuff is
__sb_start_write
ordered_mutex
but with sync() we don't do __sb_start_write for some strange reason, which
means that our iput in wait_ordered_extents could start a transaction which does
the __sb_start_write while we're holding the ordered_mutex. Fix this by using
delayed iput in sync. Thanks,
