initramfs: panic with memory information
On systems with large amounts of reserved memory we may fail to
successfully complete unpack_to_rootfs() and be left with:

panic() calls with a surrounding show_mem() such that we have a chance of
understanding the memory conditions leading to these allocation failures.
