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")
