This patch is a fix to
mm-add-a-basic-debugging-framework-for-memory-initialisation.patch pointed out
by an off-list reviewer. The intention of the code was to change the printk
loglevel depending on the message level passed to mminit_dprintk(). What
actually happens is that for MMINIT_WARNING and levels, only the loglevel
is sent to printk() and not the message. This patch fixes the code to behave
as intended.

It can be folded safely into
mm-add-a-basic-debugging-framework-for-memory-initialisation.patch without
causing collisions later in the set.
