Qu Wenruo e98bf64f7a btrfs: add extra sanity checks for create_io_em() 
The function create_io_em() is called before we submit an IO, to update
the in-memory extent map for the involved range.

This patch changes the following aspects:

- Does not allow BTRFS_ORDERED_NOCOW type
  For real NOCOW (excluding NOCOW writes into preallocated ranges)
  writes, we never call create_io_em(), as we does not need to update
  the extent map at all.

  So remove the sanity check allowing BTRFS_ORDERED_NOCOW type.

- Add extra sanity checks
  * PREALLOC
    - @block_len == len
      For uncompressed writes.

  * REGULAR
    - @block_len == @orig_block_len == @ram_bytes == @len
      We're creating a new uncompressed extent, and referring all of it.

    - @orig_start == @start
      We haven no offset inside the extent.

  * COMPRESSED
    - valid @compress_type
    - @len <= @ram_bytes
      This is to co-operate with encoded writes, which can cause a new
      file extent referring only part of a uncompressed extent.
