Subject: [PATCH 3/6] f2fs: fix to check compress file in f2fs_move_file_range()

f2fs_move_file_range() doesn't support migrating compressed cluster
data, let's add the missing check condition and return -EOPNOTSUPP
for the case until we support it.

Fixes: 4c8ff7095bef ("f2fs: support data compression")
