x86/platform/UV: Mark memblock related init code and data correctly
commit 24cfd8ca1d28331b9dad3b88d1958c976b2cfab6 upstream.
parse_mem_block_size() and mem_block_size are only used during init. Mark
them accordingly.
Fixes: d7609f4210cb ("x86/platform/UV: Add kernel parameter to set memory block size")
