On m68k, block_cache list is relocated, but next and prev list
pointers are not adjusted to the relocated struct list_head address,
so the first iteration over the block_cache list hangs.
This patch initializes the block_cache list after relocation.

As noted by Eric in the original posting, we don't need the indirection
just for the name as there's not really a hard rule about names there,
please just call the function directly, thanks!
