[PATCH] Documentation: ABI: fix "unexpected indentation" error in sysfs-block

[Jay Winston <jaybenjaminwinston@gmail.com>]

`make htmldocs` reports:
Documentation/ABI/stable/sysfs-block:612: ERROR: Unexpected indentation

Leading dashes at lines 623, 636, and 641 were considered line
continuation with errant indent and not bullet points due to
missing blank lines.  Add the blank lines.
