The code using 'ordered_extent_flush_mutex' mutex has removed by below
commit.
- 8d875f95da43c6a8f18f77869f2ef26e9594fecc
btrfs: disable strict file flushes for renames and truncates
But the mutex still lives in struct 'btrfs_fs_info'.
So, this patch removes the mutex from struct 'btrfs_fs_info' and its
initialization code.
