[PATCH] tools/mm: fix show_page() build error

[PATCH] tools/mm: fix show_page() build error

[Oleksandr Natalenko]

At one point I needed mm tools for debugging but couldn't compile them due to the
following error:

gcc -Wall -Wextra -I../lib/ -pthread -o page-types page-types.c ../lib/api/libapi.a -pthread
page-types.c: In function ‘show_page’:
page-types.c:423:49: error: expected ‘;’ before ‘if’

      |                                                 ;

make: *** [Makefile:23: page-types] Error 1

Trailing ; was forgotten, so add it.

Just FYI, a very similar patch has posted a few days ago:

OK, if the other one is taken, consider adding my Acked-by: then.

Thank you.
