Add check for the return value of memblock_alloc*() functions and call
panic() in case of error.
The panic message repeats the one used by panicing memblock allocators with
adjustment of parameters to include only relevant ones.

The replacement was mostly automated with semantic patches like the one
below with manual massaging of format strings.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
