[ Upstream commit a0bf842e89a3842162aa8514b9bf4611c86fee10 ]

Add panic() calls if memblock_alloc() returns NULL.

The panic() format duplicates the one used by memblock itself and in
order to avoid explosion with long parameters list replace open coded
allocation size calculations with a local variable.

This patch is a part of a series that removes panic() calls from memblock
allocators rather than a fix.

I've dropped it, thanks!
