[PATCH] tmpfs: fixup Docs table for huge mount options

[Randy Dunlap <rdunlap@infradead.org>]

A table's header and footer lines must match its text columns in
width, so extend the header/footer for column 1 to match the text.

Fixes this documentation build error:
Documentation/filesystems/tmpfs.rst:116: ERROR: Malformed table.
Text in column margin in table line 4.

I guess that Andrew will merge this since he merged the previous patch.
