mm: remove unused mark_page_reserved()

Browse Source 
Patch series "mm: remove three unused helpers from mm.h", v2.

I happened to notice these were unused.  Two of them are relatively
recently unused, and one has been unused for a few years.  Remove them.


This patch (of 2):

mark_page_reserved() lost its last caller in commit 6215d9f447 ("arch,
mm: consolidate empty_zero_page"). Remove it.
