Subject: [PATCH] init/main.c: add __force markup when casts to a __user pointer

add __force markup when casts to a __user address space pointer. This removes
following sparse warnings:

 init/main.c:900:23: warning: cast adds address space to expression (<asn:1>)
 init/main.c:913:25: warning: cast adds address space to expression (<asn:1>)
