From: Chao Yu <chao@kernel.org>

[ Upstream commit bb6e1c8fa5b9b95bbb8e39b6105f8f6550e070fc ]

FI_DROP_CACHE was introduced in commit 1e84371ffeef ("f2fs: change
atomic and volatile write policies") for volatile write feature,
after commit 7bc155fec5b3 ("f2fs: kill volatile write support"),
we won't support volatile write, let's delete related codes.
