[PATCH] x86/mm: Set __vmalloc_start_set in numa_32.c

[Laura Abbott]

__vmalloc_start_set currently only gets set in initmem_init when
!CONFIG_NEED_MULTIPLE_NODES. This currently breaks detection of vmalloc
address with virt_addr_valid with CONFIG_NEED_MULTIPLE_NODES=y.
Set __vmalloc_start_set appropriately for that case as well.

Fixes: dc16ecf7fd1f ("x86-32: use specific __vmalloc_start_set flag in 
__virt_addr_valid")q
