[PATCH] libfs: fix table format warning

[Randy Dunlap <rdunlap@infradead.org>]

Drop the unnecessary colon to make the table formatting correct.
The colons are not needed and this file uses them sometimes and
doesn't at other times. Generally they are not preferred in
documentation tables IMO.

Also extend the table line widths to match the table text.
