Documentation: ext4: fix cell spacing of table heading on blockmap table

Commit 3103084afcf234 ("ext4, doc: remove unnecessary escaping") removes
redundant underscore escaping, however the cell spacing in heading row of
blockmap table became not aligned anymore, hence triggers malformed table
warning:

Documentation/filesystems/ext4/blockmap.rst:3: WARNING: Malformed table.

<snipped>...

The warning caused the table not being loaded.

Realign the heading row cell by adding missing space at the first cell
to fix the warning.
