f2fs: compress: fix to avoid inconsistence bewteen i_blocks and dnode

Browse source

In reserve_compress_blocks(), we update blkaddrs of dnode in prior to
inc_valid_block_count(), it may cause inconsistent status bewteen
i_blocks and blkaddrs once inc_valid_block_count() fails.

To fix this issue, it needs to reverse their invoking order.
