Btrfs: remove unused mutex from struct 'btrfs_fs_info'
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.
