docs: fs: proc.rst: fix a warning due to a merge conflict

Changeset 424037b77519 ("mm: smaps: Report arm64 guarded pages in smaps")
added a new parameter to a table. This causes Sphinx warnings,
because there's now an extra "-" at the wrong place:

	/devel/v4l/docs/Documentation/filesystems/proc.rst:548: WARNING: Malformed table.
	Text in column margin in table line 29.

	==    =======================================
	rd    readable
	...
	bt  - arm64 BTI guarded page
	==    =======================================

Fixes: 424037b77519 ("mm: smaps: Report arm64 guarded pages in smaps")
Fixes: c33e97efa9d9 ("docs: filesystems: convert proc.txt to ReST")
