parisc: Zero-initialize newly alloced memblock
Commit 4fe9e1d957e4 ("parisc: Drop bootmem and switch to memblock") switched to the memblock allocator, but missed to zero-initialize the newly allocated memblocks. This lead to crashes on some machines like the rp3410. Fixes: 4fe9e1d957e4 ("parisc: Drop bootmem and switch to memblock") Signed-off-by: Helge Deller <deller@gmx.de>
