[PATCH] mm: Reduce mem_dump_obj() object size

[Joe Perches]

Simplify the code by using a temporary and reduce the object size
by using a single call to pr_cont().  Reverse a test and unindent
a block too.

$ size mm/util.o* (defconfig x86-64)
   text    data     bss     dec     hex filename
   7419     372      40    7831    1e97 mm/util.o.new
   7477     372      40    7889    1ed1 mm/util.o.old
