[PATCH 4.4 016/113] btrfs: print message when tree-log replay starts

[Greg Kroah-Hartman]

From: David Sterba <dsterba@xxxxxxxx>

[ Upstream commit e8294f2f6aa6208ed0923aa6d70cea3be178309a ]

There's no logged information about tree-log replay although this is
something that points to previous unclean unmount. Other filesystems
report that as well.
