Subject: [PATCH 1/1] fs/splice.c: Fix old documentation about moving pages

Since commit 485ddb4b9741 ("1/2 splice: dont steal")' (2007),
the SPLICE_F_MOVE support was removed (became a no-op according
to man pages), and thus disabling steal operation that would make
moving pages possible.

This fixes the comment, making clear pages are not moved.
