[PATCH 4.19 0/2] backport lazytime fix to 4.19

Backport a lazytime fix from upstream to 4.19-stable. The first commit had a trivial conflict in fs/xfs/ due to a file being renamed. Following that, the second commit is a clean cherry-pick.

Eric Biggers (1): fs: fix lazytime expiration handling in __writeback_single_inode()

Jan Kara (1): writeback: Drop I_DIRTY_TIME_EXPIRE
