Sebastian Ene 79c4c7284f arm64: ptdump: Don't override the level when operating on the stage-2 tables ...

Ptdump uses the init_mm structure directly to dump the kernel
pagetables. When ptdump is called on the stage-2 pagetables, this mm
argument is not used. Prevent the level from being overwritten by
checking the argument against NULL.
